Actress Jennie Garth of 90210 fame and actor Peter Facinelli from the Twilight saga and TV's Nurse Jackie will divorce after 11 years of marriage. The reason behind the divorce is not yet known, although one source believes that Facinelli had cheated on Garth on the set of Twilight: Breaking Dawn in Vancouver.

The divorce announcement comes one day after Facinelli walked the red carpet for the highly-anticipated movie The Hunger Games with his 14-year-old daughter Luca.

Garth, 39, and Facinelli, 38, originally met on the set of a made-for-TV movie, called (somewhat ironically), An Unfinished Affair. The couple married in 2001, and now have three children together, including Luca, Lola (9) and Fiona (5).
