• e-mail

They both have been featured on the cover of the iconic issue.

So it comes as no wonder Ashley Graham and Kate Upton drew so much attention at the event celebrating it.

The two stunners looked fantastic as they arrived at the Vibes Sports Illustrated Swimsuit Festival 2017.

The 28-year-old plus-sized model and 24-year-old current cover girl were joined for the Houston event by a claque of models including Christie Brinkley and  Barbara Palvin.

 Dynamic duo: Ashley Graham and Kate Upton stunned at the Vibes Sports Illustrated Swimsuit Festival in Houston, Texas on Saturday night 

Graham's figure-hugging dress featured grey diamond patterns over an off-white field and white bordering at her neckline and hem.

Her wavy hair fell free, and she'd let her flowing pine green jacket slide off her shoulders as she stood for photos.

In one, she gave the camera her best smoldering stare, placing a hand on her belly as an animated version of her in a bikini posed beneath her.

In another, she stood on a stage near an assemblage of microphones, flinging her arms up in a celebratory gesture.

Diplo and Miguel performed onstage at the festival, which featured food by a six-chef coterie including Top Chef alumni Graham Eliot and Hugh Acheson.

Graham posted a photo with a wider view of the stage being blasted with smoke, captioning 'LET'S GOOOO' and tagging Diplo.

Snap happy! Ashley took a sultry selfie on the red carpet

Yet another photo saw the first plus-size Sports Illustrated Swimsuit Issue cover girl posing in her Instagram Story alongside the svelte Barbara Palvin.

Palvin, who was the 2016 Sports Illustrated Swimsuit rookie of the year, wore a flowing and frilly white mini-dress and chugged a bottle of water.

Graham's also posted a photo of herself in profile as she stood for photos on the red carpet, one hand on her thigh and another at her midriff.

'O M F G!!!!!': This year's Sports Illustrated Swimsuit Issue cover girl: Kate Upton's Instagram page showcased her comparatively svelte figure as she posed in an elegant black dress that fell off one shoulder alongside Diplo, who played the festival that night

Belle of the ball: Upton got in her own bit of posing on the red carpet, flaunting a bit of leg through her own thigh slit and looking as though she were having a ball

Coordinated: Her nails had been painted black to match the rest of her outfit

In multiple close-up selfies posted to social media, she pouted for the camera, including one black-and-white upload captioned: 'Sweat VIBES'.

Upton's Instagram page showcased her comparatively svelte figure as she posed in an elegant black dress that fell off one shoulder.

In one photo, she posed next to Diplo, who wore a black T-shirt that opened slightly over his chest as he pointed at the camera with as mile.

'Dancing onstage with @diplo': Her arms spread wide, Sports Illustrated Swimsuit Issue legend Christie Brinkley pouted as she enjoyed the music with her 18-year-old daughter Sailor Brinkley-Cook, as well as Upton and Aly Raisman

'O M F G!!!!!' the star of the upcoming Baywatch film captioned, '@diplo that was the best party ever!!! Can I go on tour with you?! ahhhhh!!!! #diplogroupie'.

She'd also made an appearance on Brinkley's Instagram page during Diplo's set, dancing onstage with the gorgeous 63-year-old

Brinkley framed her enviably slender figure in a cleavage-baring shining green dress, baring an exquisitely toned leg from the gown's vertiginous slit.

The model glower: Meanwhile, Sailor had wriggled her way into a mini-dress with a neckline-to-hem zip that had been undone past her bust

Her arms spread wide, she pouted as she enjoyed the music with her 18-year-old daughter Sailor Brinkley-Cook, as well as Upton and Aly Raisman.

Brinkley became a legend of the Sports Illustrated Swimsuit Issue beginning in the 1970s, covering the magazine multiple times.

She'll be in the 2017 issue as well, along with Sailor - her daughter by her fourth husband Peter Cook (not the iconic comedian) - and her other daughter, 31-year-old Alexa Ray Joel, whose father is Billy Joel (none other than the famous singer).

Back at it: Nina Agdal, who was in the issue last year and will be enjoying a triumphant return this yearwore a dress with an orange-lined high collar folded down

Showing what she's got: Orange bordering snaked between the black and white sections of her dress, which stopped less than halfway down her gleaming thighs

While on the carpet, Brinkley resolutely arced her chiseled leg from her dress' opening, her hoop earrings poking through her platinum blonde hairdo.

Meanwhile, Sailor had wriggled her way into a mini-dress with a neckline-to-hem zip that had been undone past her bust.

Stripes of black separated baroquely patterned purple and orange sections from one another, and a gold choker glinted around her neck.

What to expect: Hannah Jeter, who'd covered the Sports Illustrated Swimsuit Issue in 2015, wore a sheer netted black dress that allowed a clear look at her baby bump

Hand on the hip: The wife of Derek Jeter, who married her husband last year, had a thigh slit of her own, as well as an asymmetrical hem and black ankle-strap shoes

Upton got in her own bit of posing on the red carpet, flaunting a bit of leg through her own thigh slit and looking as though she were having a ball. 

Hailey Clauson, a Sports Illustrated Swimsuit Issue cover girl last year, wore a tiny black cocktail dress speckled with gold designs.

Nina Agdal, who was in the issue last year and will be enjoying a triumphant return this year - like Clauson - wore a dress with an orange-lined high collar folded down.

Note the clutch and shoes: Raisman's silver drop earrings matched the silver bordering, including intricately designed patterning at her cuffs, of her off-white mini-dress

Orange bordering snaked between the black and white sections of her dress, which stopped less than halfway down her gleaming thighs.

Samantha Hoopes, who in 2014 was in Sports Illustrated's 50th Anniversary Swimsuit issue, smoldered in a black cocktail dress with a rectangular neckline.

In addition to baring some decolletage, she allowed a bit of thigh to show through, framed by long black boots and her perilously high hemline.

The plunge: Hannah Ferguson, who'll be in this year's Sports Illustrated Swimsuit Issue, wore a black dress that glinted in the lights above its pleated waistline

Barely there: Hailey Clauson, a Sports Illustrated Swimsuit Issue cover girl last year, wore a tiny black cocktail dress speckled with gold designs

Raisman's silver drop earrings matched the silver bordering, including intricately designed patterning at her cuffs, of her off-white mini-dress.

A silver clutch was held against it and silver ankle-strap stilettos augmented the look. She'd slicked her hair back and otherwise allowed it to fall unfettered.

Legend: Christine Brinkley signed autographs at the event

Fresh-faced: Kate looked bright-eyed at the signing session

Thirsty work: Bianca Balti took a sip from her drink mid-talk

Stunning: Barbara Palvin showed just why she's so highly rated

Work it: Kate Bock posed with a copy of the magazine

Pleated fabric also framed the neckline, which fell to her taut midriff, as well as draping over her padded shoulders and winding about her cuffs.

Her dress opened in a thigh slit such that it resembled a robe, and through the gap, she slid a leg she'd pushed into a heavily studded black stiletto boot.

Hannah Jeter, who'd covered the Sports Illustrated Swimsuit Issue in 2015, wore a sheer netted black dress that allowed a clear look at her baby bump.

One armed featured a ruffled strip of fabric that wound down its sides and sloped around her elbow, and the other arm was without even the semblance of a sleeve.

The wife of Derek Jeter, who married her husband last year, had a thigh slit of her own, as well as an asymmetrical hem and black ankle-strap shoes.
