"Transformers" star Megan Fox filed for divorce from actor Brian Austin Green on Friday after five years of marriage, a Los Angeles court spokeswoman said.
The filing in Los Angeles Superior Court came after media reports earlier this week that the couple had separated.
Fox, 29, is best known for starring in the blockbuster "Transformers" movie in 2007 and a 2009 sequel. In 2008 she was named the world's sexiest woman in a poll by the magazine FHM.
She has said she met Austin Green, who appeared in the 1990s television show "Beverly Hills, 90210," when she was 18 and he was 30. They went on to date for years and married in 2010.
The couple have two children together.
Theirs is just the latest in a string of celebrity divorces announced recently.
In early August, singer Gwen Stefani filed for divorce from rockstar husband Gavin Rossdale after 13 years of marriage, citing irreconcilable differences. She also asked for joint custody of the couple's three children, 9-year-old Kingston, 6-year-old Zuma and 1-year-old Apollo.
This was preceded by the split of Hollywood couple Ben Affleck and Jennifer Garner in July, who celebrated their 10-year wedding anniversary in the saddest way - a divorce.
