London: Singer Mandy Moore's mother, Stacy, has been reported by a US tabloid as being romantically involved with another woman.

Contactmusic.com reports that Stacy left her husband for tennis professional Claudette Laliberte and has been dating her secretly since 2006. The two are reportedly living together.

The tabloid claims that the affair came to notice last year after Laliberte's lover discovered the emails between the two women.

When confronted by the magazine about her relationship, Stacy said: "It is nobody's business why we are together."
