Kate Walsh's New Boy Toy -- And It's Not Dave Annable!

You can kiss those Dave Annable (Brothers & Sisters) rumors out the window, there’s a new boy toy in town!

Sassy redhead Kate Walsh, aka Dr. Addison Montgomery, finds love in the arms of a Alex Young, a production co-president at 20th Century Fox, on Saturday afternoon in Los Angeles.

The 39 year-old Grey’s Anatomy star, who recently took out her bangs, spent the morning at Radford Hall for a personal meeting.

The new dirty blonde beau then met up with Kate for lunch at the Mustard Seed Cafe (Rachel Bilson just ate there on Thursday).

Kate was not shy about kicking up her feet into her man’s lap in between affectionate kisses. The lovebirds took their PDA-fest to the next level in his Porsche, where things looked like they got hot and heavy!

“We’ve been together for a while and he’s just a dreamboat,” Kate has said. “He’s my man.”
