January Jones' baby daddy mystery deepens

January Jones has been trying to keep the identity of her baby's father hidden. But a new rumor suggests the baby daddy may not be who you think. So, who is it?

January Jones pregnant

When the news broke that Mad Men star January Jones was pregnant, everybody wanted to know who the father of her unborn child was. So far, rumors of parenthood have swirled around Jason Sudeikis, the Saturday Night Live star who dated January Jones until January of this year. But, is Sudeikis really the father?

Not so, says E! Online's Ted Casablanca. "According to very well placed movie insiders, closely connected to Jones (who was shooting X-Men: First Class in the UK), January was involved with someone on set -- and that someone is the father of her child," Casablanca revealed.

So, who might that be? Well, if it's one of the male stars of the X-Men prequel, it could be any number of Hollywood actors, including James McAvoy, Michael Fassbender and Kevin Bacon.

Let's see, Bacon and McAvoy are married, so that leaves Fassbender, one of the crew members, or someone on the production team. Pretty much, it's anybody's guess! And January's not saying.

At least all this confusion explains Sudeikis' awkward response when a reporter at the White House Correspondents' Dinner asked the comedian if he's the father-to-be.

"I'd rather -- yes but no," Sudeikis said. Asked if he was surprised his ex was pregnant, he replied, "No, I -- no, I didn't have anything [else to say]."

Who do you think January's baby daddy is?
