J.Lo’s producer fight; Lenny Kravitz cancels tour; Madonna saves dad’s winery: “George Clooney is petrified about shaving his head for his latest role — because he’s afraid it won’t grow back.

The 43-year-old Hollywood heartthrob is set to go bald and pile on the pounds for a solider role in ‘Syriana,’ a movie about the CIA’s war on terrorism.

A friend says, ‘George has no problem with putting on a few pounds — in fact he’s looking forward to it.

‘What he is a little freaked out about is shaving his head. He’s been worried about going bald and someone told him that if he shaves his hair off then it might not grow back the same.’

‘He might just crop it now, or maybe wear a skullcap.'”
