Actress Shannen Doherty has devastated her father by telling him reports she's dating US college sports hero Matt Leinart aren't true.

The former BEVERLY HILLS 90210 star and her dad are huge fans of top-rated American football team the University of Southern California Trojans, and when he heard his daughter was dating quarterback Leinart, he was thrilled.

Doherty says, "That would be the perfect son-in-law. My dad was like, 'Oh my God, is it true, is it true? Matt's going to be my new son-in-law.' He was so excited.

"Matt is handsome and he is talented and he is a great quarterback, but the truth of the matter is he was in the same club (as me) - and that was it."
