Gillian Anderson by Mike Marsland/WireImage.com
The X Files: I Want to Believe
is pregnant with her second child with boyfriend Mark Griffiths, says
The couple already has a baby son named Oscar, who was born in November 2006, and Anderson has a 13-year-old daughter, Piper, from her previous marriage to Clyde Klotz.
A budding belly might explain the loose, towel-like dress Anderson wore to the Cannes Film Festival while promoting her film,
How to Lose Friends and Alienate People
. Plus, she did have that lovely, "I'm pregnant" glow.
The X-Files: I Want to Believe
opens July 25.
