BREAKING NEWS - January Jones Is Pregnant!

January Jones has just announced she's going to be a mom!

The X-Men: First Class star's rep said in a statement:

"January Jones is happy to announce that she is expecting her first child this fall."

Jones is keeping the baby daddy's identity a secret, and it's unclear exactly how many months along she is.

The Mad Men star has most recently been linked to Saturday Night Live cast member Jason Sudekis, but they reportedly broke up in January.

Maybe that's why we caught Jones covering her belly just a few days ago while shopping at the mall (click through our pics to check it out). The teeny-tiny star usually wears much tighter clothing!
