Friends of Owen Wilson and Kate Hudson are said to be less than enthusiastic about the couple's newly rekindled their relationship.

While the pair has reportedly been busy in Miami getting cosy behind closed doors, pals have been airing their reservations to a U.S. magazine.

One tells OK!: "Kate fell for Owen so hard that she risked everything and went head first into love with him," a friend of the actress tells OK!. "But even during the year they were together, it was a roller coaster. I hope what's going on now is just temporary.

"They're both busy with movies, and hopefully Kate will have some clarity and decide to just be friends with him," continues the friend. "I'd be very, very worried if they got back together seriously. It is ridiculous for her to think he's all better in eight months."

Owen is in the city filming new movie Marley and Me, while Kate flew in to attend the Miami International Film Festival.

Both have been careful not to be snapped together in public.
