Yet another celeb to add to the baby bump list is X-Files star Gillian Anderson. According to People, the 39-year-old actress is preggers with her second child with boyfriend Mark Griffiths. The couple have a son, Oscar, who was born on November 1, 2006.

Gillian's latest film, The X-Files: I Want to Believe will hit theaters on July 25.

Seems like being pregnant and having a movie out this summer is a big trend! I mean, Michelle Monaghan just announced she was preggers two days ago!
