Mark Ronson Dating Blossom?

No, he isn’t dating Mayim Bialik, but he sure as hell is dating her lookalike circa 1984!

Mark Ronson was seen with his latest girlfriend, hocialite Josephine de La Baume, as they made their way to have dinner at Nobu in London on Monday.

Honestly, Mark, you can do so much better. This girl looks like last week’s trash next to you.

You don’t have to lower your standards anymore. You are a celebrity!
