"The Office" star showed off her baby bump while on vacation for her 40th birthday. "Thanks for all the sweet birthday messages. I think I found a good place to celebrate!," she posted on Twitter along with the revealing snap.
Sporting a blue bikini top and white slacks, the brunette beauty looked like she was having a great time soaking up the sun at the beach.
This will be the second child for Fischer and husband Lee Kirk who already have a 2-year-old son, Weston, together.
The "Blades of Glory" star is normally pretty covered up, and we think it's great that the actress is proud of her pregnancy curves!
