Ali Fedotowsky: Flirting With Matt Leinart!

A former USC Trojan, football star Matt Leinart may be putting his former mascot to use in a different way with Ali Fedotowsky ... if you know what we mean!

We mean sex. Protected style.

Rumors are circulating that The Bachelorette star does not find love and happiness and picks no one the finale of the reality show Monday night.

Might this be further proof?

According to Star, when Ali met the Arizona Cardinals quarterback at a July 15 at a charity event, sparks flew after they talked "by themselves."

Ali Fedotowsky and Matt Leinart pose for a photo. Oooh!

By the end of the night, the jock scored Ali's digits: "Matt finally asked for Ali's phone number and she happily gave it to him," a witness says.

"He promised that he'd call her; she must be over the moon about catching the eye of such a hot guy!" Well, unless she's engaged, of course.

There are rumors if her rejecting both guys, or that Roberto Martinez proposes, but they didn't make a go of it and she's already single again.

We also theorize that perhaps she still hasn't decided.

Guess we'll find out soon enough ... and we may very well be surprised. But we would be astonished if Matt Leinart were at all a factor in this.
