Baby on board.

Dressed in baggy clothes, mommy-to-be January Jones grabbed a quick lunch at the Sunset Towers Hotel in Hollywood Friday afternoon.

On Thursday, a rep for the Mad Men star, 33, told Us Weekly that the actress "is expecting her first child this fall."

The rep added that Jones plans to raise the child as a single mother.

No word yet on if this will change things up for alter ego Betty Draper on the AMC hit.
