Some people like to give Red Sox owner John Henry a hard time for having a young wife, or question why Pats poobah Robert Kraft is out and about with a woman half his age. We can only imagine what they’ll say about Aerosmith’s 64-year-old singer, Steven Tyler, who was photographed going to dinner this week with Francesca Eastwood, the 19-year-old daughter of filmmaker Clint Eastwood. The pair, who looked like they didn’t want to be photographed together, joined Jim Carrey and Russell Simmons at the LA restaurant Little Door. Tyler is single again after recently splitting with fiancee Erin Brady. Eastwood, who’s sometimes described as an actress, or a model, or a socialite, is best known for starring on the E! reality show “Mrs. Eastwood & Company.”
