Billy Bob Thorton, is that you?

Mickey Rourke grabbed lunch at E. Baldi in Beverly Hills yesterday, and The Wrestler star appears to have done something to his teeth, because we almost mistook him for Angelina Jolie's former husband!

The legendary actor brought along his new pooch on the outing, and we're happy to see that he's bouncing back with another furry friend after the death of his beloved Chihuahua Jaws last year. The quirky 62-year-old has credited canines with renewing his will to live after hitting a low following his divorce from Carrie Otis in the 1990s.

"I think I hadn't left the house for four or five months, and I was in a bad place...then I looked at my dog, Beau Jack, and he made a sound, like a little almost human sound. I don't have kids, the dogs became everything to me. The dog was looking at me going, "Who's going to take care of me?'" he confessed to Barbara Walters in 2009.

Such a small dog for such a tough guy!
