'X-Men: First Class' star January Jones is pregnant, her rep exclusively reveals to People (via our pals at PopEater).

"January Jones is happy to announce that she is expecting her first child this fall," her rep told the magazine.

The 33-year-old is currently single and hasn't revealed any other details, including who the father is. "She's really looking forward to this new chapter in her life as a single mom," her rep added.

Jones broke up with 'Saturday Night Live' star Jason Sudeikis in January. "They've been on and off for a few months, and then the long distance kind of ended it," a source said at the time. "But they could get back together. It was just hard to stay together with the distance."

Jones lives primarily in Los Angeles, where her hit show 'Mad Men' films. Sudeikis calls New York City, where he's a regular on 'SNL,' home. Sadly for this cute couple, a bicoastal romance proved too difficult to maintain.

Sudeikis will host the MTV Movie Awards in June.

The blond starlet will next be seen onscreen in superhero flick 'X-Men: First Class,' due in theaters June 3.
