Saverio Merone/LaPresse/ZUMAPress.comThe truth is out there—the baby's in there.
Gillian Anderson is expecting her second child with boyfriend Mark Griffiths, the actress' rep confirms to E! News.
No due date has yet been revealed and it's unclear how far along the once and future Dana Scully is.
This will be the second child for Anderson and Griffiths, who already have 19-month-old son Oscar. She also has a 13-year-old daughter, Piper, from her personal ex-file, former husband Clyde Klotz.
One due date the 39-year-old mother-to-be has nailed down, however, is that of her highly anticipated film, X-Files: I Want to Believe, due out July 25.
