Demi Lovato and boyfriend Guilherme Vasconcelos emerge from DNCE concert where they saw her ex Joe Jonas perform

Demi Lovato and her latest boyfriend Guilherme Vasconcelos enjoyed a Los Angeles night out on Wednesday, taking in a DNCE concert at the Belasco Theatre.

The pair were spotted post-show, heading into their car. Both members of the couple sat at the back as they were driven from the venue.

Streaks of silver ran down the sleeves of Lovato's otherwise black gleaming jacket, and she'd pulled herself into a pair of seemingly airtight black leggings.

He'd popped on a black baseball cap, matching his black leather jacket and a black T-shirt that clashed elegantly against his white trousers. 

Though DNCE includes Lovato's ex Joe Jonas, the used-to-be's appear on good terms, to the point she performed with his band last September.

In fact, when the UFC fighter posted an Instagram photo on Wednesday in which he'd flung an arm about his girlfriend, Jonas was among those who liked it, per Entertainment Tonight.

Onstage at the Belasco, the elder brother of Nick Jonas had slicked his hair to one side and flung on a dark jacket spattered with white spots.

His jeans featured matching spots and a tear over his right knee, and he'd allowed a fair amount of stubble to sprout across his face.

DNCE, which along with Jonas includes JinJoo Lee, Cole Whittle and Jack Lawless, released their first EP, entitled Swaay, in 2015.

After the end of her six-year relationship with Wilmer Valderrama, there'd been rumours Lovato was dating the man known as 'Bomba' last summer.

In June, Bomba reposted a Bellator MMA Instagram video in which she embraced him, saying: 'You did it!' after he'd won a fight at the Scottrade Centre in St Louis.

Earlier in June, a selfie showed her sat beside him, the pair of him smiling, and Bomba captioned: 'After I sparred with a legend @xcnatch.. The one who hit my lip and made me bleed was @ddlovato hehehe...'

By the middle of the following month, however, People were quoting a source who'd dished that 'They had a quick fling but it’s over now.'

In the interim, she had a relationship with Luke Rockhold, another UFC fighter, but on January 3, TMZ reported they'd gone their separate ways.

She and Bomba appear to have reignited their romance as early as New Year's Eve, when he shared a selfie of the two of them in festive accessories, captioning: 'Happy new year !!!!'

Another UFC man: By July, however, People reported she and Bomba had split, and she went on to date Luke Rockhold in the intervening time, until TMZ heralded the end of that relationship on January 3
