Kind of a weird thing to joke about, but ok!

January Jones has never revealed the father of her son Xander, but in the new issue of Playboy, her pal James Marsden confessed that he and the Mad Men actress poke fun at the rumors he is the dad!

"Every time I see January, she's like, 'Hey, father of my baby," he told the mag.

So how did the ridiculous chatter begin?

"There's so much stupid talk out there. I think that came from somebody thinking we were both in X-Men so it must be true," he added.

We still think her little boy looks exactly like her ex Jason Sudekis!
