Gillian Anderson is pregnant. The 'X-Files' actress, who already has two children, and her boyfriend Mark Griffiths are expecting another child, Gillian's representative has confirmed.

The flame-haired star first sparked rumours she was pregnant after sporting what appeared to be a baby bump at the Cannes Film Festival in France last month. It is not yet known when she is due to give birth. Gillian and Mark have a 19-month-old son Oscar together.

The 39-year-old star also has a 13-year-old daughter, Piper, from her previous marriage to photojournalist and filmmaker Julian Ozanne. Gillian's next big screen appearance sees her reprise her role as agent Dana Scully in 'The X-Files: I Want to Believe' - the second big screen adaptation of the hit 90s US TV show. The movie will be released worldwide next month.
