Gillian Anderson has her own Odd Couple

Cast member Gillian Anderson poses at the movie premiere of ''The X-Files: I Want to Believe'' at the Grauman's Chinese theatre in Hollywood, California July 23, 2008.

LOS ANGELES (Reuters) - "X-Files" star Gillian Anderson has evidently drawn inspiration from "The Odd Couple" when it comes to naming her sons.

The 40-year-old actress has given birth to a boy named Felix, People magazine reported on Monday, almost two years after she delivered her first son, Oscar.

"The Odd Couple," a Broadway play written by Neil Simon in 1965, revolved around a neurotic newswriter named Felix and a slovenly sportswriter named Oscar who are forced to live together. A 1968 feature film starred Jack Lemmon and Walter Matthau in the respective roles.

Anderson gave birth to Felix in London on October 15, People said. The father of both boys is her boyfriend, businessman Mark Griffiths. She also has a 13-year-old daughter, Piper, with the first of her two husbands.

Anderson was in movie theaters this year with two commercial disappointments, "X-Files: I Want to Believe," the second film based on the hit sci-fi TV series, and "How to Lose Friends & Alienate People."
