Can you guess who Russell brand fancies? One hint: It's not any of his Forgetting Sarah Marshall co-stars…

Ladies' man Russell Brand seems to like the blondes. He told Nuts he has celebrity crushes on Christina Aguilera and Uma Thurman. No word on how he feels about his Forgetting Sarah Marshall co-star Kristen Bell.

"I met Christina Aguilera before she was pregnant," said Brand. Then he jokingly added, "Although I was releasing a lot of spores that day, I don't think the baby's mine. I can't make any claims to it."

We don't think Christina's husband Jordan Bateman would appreciate that very much!

Russ sounds more awed by 6-foot-tall beauty Uma. He said, "Uma Thurman is lovely. She's like a gorgeous statue that's come to life. I just want to crawl up onto her lap and pretend to be a baby."

Cheeky! Can Russell ever stop kidding around?

Forgetting Sarah Marshall is in theatres April 23.
