Mandy Moore’s mom is a lesbian, spywitness for The National Enquirer spill.

Stacy Moore, mother of the straight-laced singer/actress, left Mandy’s dad in 2006 after carrying on a sordid same-sex affair with tennis pro Claudette Laliberte. The two began living together in 2007.

“It’s nobody’s business why we’re together,” Stacy Moore told The Enquirer when quizzed about her sexuality.
