Brad Pitt speeds away from clingy Angelina?

Brad Pitt has taken to speeding off on his motorcycle to spend time alone, gossips claim.

“Angelina has become this clingy woman,� an insider tells Star. “The more she clings, the further away Brad gets. He likes to take off on his motorcycle when the strain of living with her gets to be too much and when caring for all the kids wears him out. Angelina is worried that Brad might just keep going one day and her for good.�

On July 9, Brad took off on a solo motorcycle ride from Prague to Berlin. Just days later, he interrupted a vacation in France with Angie and the kids to take off to Berlin again.

“There seems to be little intimacy between Angie and Brad any more,� says a source. “A lot of it is because of Angelina. She used to be this exciting woman. Now she seems cold, withdrawn, aloof and lethargic. Brad finds himself pulling back.� While he has tried his best to be sympathetic and supportive, insiders say, Brad is at his wit’s end.

Angie appears to have become anti-social, sources say, skipping the July 15 wrap party in Prague for her movie, Wanted, and turning down invitations from friends. “Brad must be feeling suffocated by her,� says the insider. “She often refuses to socialize with any of Brad’s friends or with their significant others and their kids.

“It’s come to the point where if Brad wants to see his friends, he has to do it on his time, not hers. This seems to be another reason he goes off on his own. She wants him to be as reclusive as she is, and that’s just not him. The strain is getting to Brad.�
