Hollywood sure is a small town. "Family Guy" overlord-turned-"We Saw Your Boobs" crooner Seth MacFarlane is reportedly dating a woman who procreated with Reese Witherspoon's ex-husband.
"It's been going on for a little while," says a source. "It's very casual, but they are hanging out and he is having fun with her."
According to the snitch, they've been acquainted for about three years but have grown closer in recent months. Earlier this year, Knapp contributed her voice to the Valentine's Day episode of "Family Guy."
"They always had good chemistry," explains the insider. "Alexis' star is on the rise. He thinks she's really talented."
Adds a spy to People, "They've known each other and have been friends for years. She's very bright and loves science like him. She's down-to-earth and sweet."
But a MacFarlane source pooh-poohs the romance rumblings to E!, noting that he's been "extremely busy" on an out-of-town production.
In April, the Peter Brady doppelganger sparked hookup rumors when he was spotted dining with Charlize Theron, but insiders were quick to insist that they were just friends.
