They've been inseparable since they met while filming the MTV show Just Tattoo Of Us, and were rumoured to be kissing during a recent night out.

But Stephen Bear is still continuing to deny rumours that he's dating Charlotte Crosby, despite admitting she is 'funny, witty, clever and gorgeous'.

The Ex On The Beach star, 27, claimed that they weren't together because of timing, but couldn't resist cheekily quipping that she was pregnant with his child.

Not a thing? Stephen Bear is still continuing to deny rumours that he's dating Charlotte Crosby, despite admitting she is 'funny, witty, clever and gorgeous'

The CBB star told OK! Magazine: 'Charlotte ticks a lot of my boxes – she's funny, witty, clever, she's got all the right attributes, but as I'm filming Celebs Go Dating.

'It's a case of right girl, wrong time. But who knows what will happen in the future.

Making light of the situation, he joked: 'She's pregnant with my baby!' 

Stephen insisted he's single as he prepares to appear on dating show Celebs Go Dating, but added that after the series he would ask Charlotte out as she's 'gorgeous'. 

It comes as Charlotte packed on the PDA with her rumoured boyfriend at the MTV Brand New gig at Camden's Electric Ballroom last Friday night.

Speculation: Charlotte hid under the covers with just her hand visible clutching her phone in the video  

The pair have been linked romantically for months, but appeared to confirm their relationship earlier this week by sporting matching 'His and Hers' jumpers - which Bear was still sporting in Camden. 

An insider told The Sun: 'Bear and Charlotte have been snogging loads on set for Just Tattoo Of Us and have hardly kept it a secret to the crew.

'It's clear they are besotted with each other.'

However, with Bear set to appear on Celebs Go Dating, his rumoured romance with Charlotte throws a spanner in the works. 

A source said: 'Bear is doing Celebs Go Dating which puts him in an awkward position to be in a relationship.

More than friends? They grey close while filming MTV show Just Tattoo Of Us

Just pals? The pair became close during filming for their new MTV show Just Tattoos Of Us

'This is why they’ve been keeping things under wraps as much as possible in public, even though it’s clear they are together and have strong feelings for each other.'   

And last week Charlotte and Stephen seemed to take their romance to the next level, as they were captured giggling and cuddling in bed.

Stephen sent the romance rumour mill into overdrive as he larked around with the Geordie Shore star in a steamy Snapchat video - but deleted the clip minutes later.

In the racy video, Stephen seemed to be topless as he got cosy with a laughing Charlotte, who hid under the covers.

The pair seemed suddenly shy as they tried to conceal themselves under the duvet.

Despite being live for around 15 minutes, fans were quick to share photos from the clip on Twitter - speculating that the pair are now dating.    

A source denied the rumours however, telling MailOnline: 'Charlotte and Bear are filming pick ups for Just Tattoo of us today.

'Production had booked them rooms in the same hotel last night so they had food and watched TV together for a couple of hours which was when bear posted that snap. 

'Charlotte was fully clothed under the covers. 

Despite the recent development in the are they/aren't they rumours swirling around the reality stars, Charlotte has insisted they aren't dating. 

Appreciative: Charlotte previously claimed Stephen was 'very funny and full of charm' - but insisted that they were 'just very good friends'

'We're just very good friends,' she previously told Heat magazine.

'We spend a lot of time together, but that was just filming 16 hours a day for Just Tattoo of Us.

'When we were filming, we were constantly play-fighting with each other, or doing something to wind each other up,' she added.

The Geordie beauty added that she could understand why so many women - including Vicky Pattison, Chloe Khan and Lillie Lexie-Gregg had fallen under his spell. 

A sign? Charlotte posted a bathroom selfie on Instagram wearing nothing but a white hoodie emblazoned with 'His...' in bold black print and captioned it, 'I'm his ❤'

'He is very funny, and he has a lot of charm,' she admitted. 'So yes, I can see the attraction.'

And Charlotte's best friend and former Geordie Shore co-stars Sophie Kasaei revealed they definitely have 'chemistry'.

Writing in her new! magazine column that the pair aren't in a relationship but have probably had 'a cheeky neck on', she explained that Charlotte is nervous about going public with a new man.

Sophie said: 'She's very stupid and vulgar, and he's exactly the same. They're a match made in heaven! They'll have the most hilarious time together.'
