January Jones Pregnant: Father Is a Mystery

May 2, 2011— -- By announcing her pregnancy on the day of the royal wedding between Prince William and Kate Middleton, perhaps "Mad Men" actress January Jones was hoping the news would get overlooked.

After all, Jones split from boyfriend and "Saturday Night Live" star Jason Sudeikis in January. And she's keeping quiet about who the baby's father is.

"January Jones is happy to announce that she is expecting her first child this fall," her rep said in a statement.

It appears the 33-year-old actress will be raising the child on her own. A source close to Jones told People magazine, "She's really looking forward to this new chapter in her life as a single mom."

Jones plays married mother of three Betty Draper on the hit AMC show "Mad Men" and is set to play Emma Frost in the upcoming "X-Men: First Class."

She has been linked to several famous men during her career, including Jeremy Piven, Adrian Brody, Jim Carrey, singer Josh Groban and oil heir Brandon Davis.
