Yet Ryan Gosling, nominated in the Best Male Performance, Best Gut-Wrenching Performance and Best Kiss categories at the MTVMAs, headed out of Los Angeles with his girlfriend of nearly one year, Eva Mendes, which is a closely guarded secret.

Mendes famously got the giggles when asked about Gosling on the Ellen DeGeneres show.

Showing a clip of Gosling, working out in onesie PJs on an episode of Ellen, the host pointed out that Mendes was also a big fan of the relaxing nightwear.

"I don't know if you ever run into him, if you know him in any way, or see him ever," DeGeneres jokingly told Mendes on her show, suggesting she should ask him about the pyjamas.

Mendes, who kept a straight face at this point, told DeGeneres, "So ask Gosling about the onesie. Okay, note to self. Ask Gosling about the onesie."

But it was the TV personality's next question that brought out the actress's flushed side.

"So you just call him by the last name?" DeGeneres asked. "You don't call him Ryan? You just call him Gosling - when you see him ever?"

Blushing, Mendes put her head in her hands and covered her face with hair as a set assistant brought out a pink onesie for Mendes and a purple one with duckies for Gosling.

"Because he likes them so much, when you see him - if you see him if you run into him - I've got a gift that I think both of you would have fun [with]," DeGeneres joked once again. "[This could] especially [work] as an icebreaker when you meet him for the first time."

Mendes has stated that she does not want to have children and has described marriage as "a very archaic kinda thing. I don't think it fits in my world today."
