Mandy Moore has been caught up in tabloid expose after her mother, Stacy Moore, is being reported by a U.S. tabloid as being romantically involved with another woman. According to a report by the National Enquirer momma Moore is a lesbian and left her former husband for tennis pro Claudette Laliberte.

The same-sex couple reportedly have secretly been dating since 2006 and even set up a home together. The tabloid claims the affair surfaced last year after Laliberte's lover discovered emails between the two women.

There's no word from Mandy's camp on the matter, but when being quizzed about her relationship with Laliberte, Stacy told the Enquirer, "It's nobody's business why we're together."

In addition to Mandy, Stacy also has two sons; Scott Moore and Kyle Moore, with hubby Don Moore. As of Laliberte, she's been reported to have recently worked as professional tennis coach for the City of Sedona Parks and Recreation.
