Though Ryan Gosling and Eva Mendes appear to still be together, the relationship could be in jeopardy as the actress has found herself the apparent object of someone else's affections -- another woman's.

Ryan Gosling Cheating On Eva Mendes?

According to The Daily Star, The Only Way is Essex star Lauren Pope was spotted at MClub in Belfast, Ireland over the weekend, snuggling up to a sultry photo of Mendes while partying, following a fall-out with her co-stars.

"Just hangin with Eva Mendes #t-tgrab," Pope captioned an Instagram photo of herself cozying up to a wall photo of Mendes and placing her hand over the actress' right breast.

Eva Mendes Spotted Out In Ryan Gosling's Shirt As Break-Up Rumors Continue?

Pope isn't the only celebrity to express an interest in Mendes, who has been dating Gosling since 2011. In March, Hollywood heartthrob George Clooney reportedly made it clear that if Mendes ever found herself single again that he would be extremely interested in dating her.

"George would give his right arm to date Eva," a source allegedly told Hollywood Life at the time. "He's run into her a few times over the years and loves her energy. He says he could talk to her about anything since she's hugely intellectual, and he's turned on by her smarts."

Mendes could be on the market again soon if she chooses to end things with her current beau, who has been rumored to be back in touch with his ex-girlfriend and The Notebook co-star Rachel McAdams.

Sources told OK! Magazine in March that McAdams was trying to win Gosling back, and that he has been somewhat receptive to the idea.

"Rachel has been very low-key about it all," the source said at the time. "She's played it very smart and used the whole 'just friends' angle to get close to Ryan again, but she 100 percent wants him back. He' not the cheating type, but he hasn't been honest with Eva about how much contact he has with Rachel."

Though Gosling isn't allegedly the cheating type, a recent Cosmopolitan article claimed he could be a cheater simply because of his name. The website quoted a poll of 2000 women on siteopia.com, which pegged the top ten names of men who are most likely to cheat on a partner.

Ryan came in third on the list, behind Wayne and Liam. The other names included Matt, Craig, Steve, Scott, Dean, Mark and Lee.
