Jennifer Aniston 'Becoming Clingy'

Jennifer Aniston's pals fear she is becoming "clingy" in her relationship with John Mayer.

The actress' friends are said to be glad she has found a man she can be happy with, but are worried "clingy Jen" is re-emerging.

A source is quoted by MSNBC.com's The Scoop as saying, "It took Jen a long time for her to get over Brad (Pitt) and even a longer time to get out of the habit of just going along with whatever the guy wanted. Now it looks like the 'clingy Jen' is back.

"John puts on this act in his blog but he likes being followed around and all of the attention. He's a typical rock star that way. Jen feeds right into it."

But the source adds, "They're really into each other. John's definitely different with her than he's been with other girls, so maybe it will last.."
