The 'X Files' star has given birth to her third child in London, England. People.com reported that the boy is healthy and well and that both Anderson and her long time partner Mark Griffiths are thrilled.

Anderson's representative Kelly Bush told the website that the baby weighed 6 lbs, 15 oz. The couple have named the child Felix, coming almost two years after her first son which they named Oscar.

It is thought that the inspiration is derived from the two lead characters in the hit 1968 comedy 'The Odd Couple' which starred Jack Lemmon as Felix Ungar and Walter Matthau as Oscar Madison. Anderson also has a 13-year-old daughter (Piper) from a previous marriage.
