Gillian Anderson wishes she could "control" her accent.

The Chicago-born actress grew up in London and admits she finds it bizarre that her dialect switches rapidly from British to American without her intending to.

Gillian Anderson is planning to move back to America. The "X-Files" actress has been based in London with partner Mark Griffiths and their children - one-month-old Felix, two-year-old Oscar and 14-year-old Piper, Gillian's daughter from her marriage to Clyde Klotz - but is now considering returning to her homeland following Barack Obama's election as U.S. President.

A source close to the 40-year-old star revealed to Britain's Daily Express newspaper: "Gillian has enjoyed living in London in recent years but made it clear she'd consider moving back to the U.S. if Obama won."

Gillian Anderson welcomed a baby boy into the world on October 15, her representative has confirmed.

"The X-Files" star - who has a one-year-old son Oscar with boyfriend Mark Griffiths and a 13-year-old daughter Piper from a previous marriage - gave birth to Felix Griffiths, who weighed 6lbs 15oz, in London earlier this month.

Gillian Anderson - who was eventually cast as paranormal FBI investigator Agent Scully in the hit US TV show - admits bosses approached former "Baywatch" actress Pamela before they offered her the role.

She said: "Pamela was somebody who was more familiar to them in terms of what was on TV at the time."
