Kate Hudson has rushed back to Florida after gossips revealed the heat between Jennifer Aniston and Owen Wilson on the Miami set of the upcoming film Marley & Me, Star reports

"When Kate heard that Owen was going to work with Jen, she wasn't worried, because she thought Jen was older and not Owen's type," says an insider. Plus, the two women have been friends for years. "Besides, Jen used to date Vince Vaughn, and Kate knows that Owen is Vince's good friend and that Vince still cares for her. But once Owen started raving to Kate about Jen, saying how cool and pretty she is and how much he liked working with her, Kate got worried."

Eyewitnesses in Miami say that Owen and Jen are growing closer as they play an on-screen husband and wife.

"They're laughing all the time and always touching and hugging, even when the cameras aren't rolling," says a source. "Their connection is amazing!"
