Singer/actress Mandy Moore has hit back at claims she lost her virginity to actor Wilmer Valderrama, insisting he's lying about his conquest. The actor appeared on the raunchy Howard Stern radio show last month (APR06), and talked explicitly about his love life. Valderrama boasted he was the first to sleep with CANDY singer and also claimed to have had sex with Lindsay Lohan, Ashlee Simpson and Jennifer Love Hewitt. Moore maintains the claim is "utterly tacky, not even true, and it hurt my feelings because I like him." Love Hewitt has also lashed out at the THAT 70's SHOW star saying, ""I was told that we had all these very steamy encounters and I was like, 'Really! Well, I would have loved to have been there!'"
