Actress Natalie Portman was stunned when Charlize Theron rushed over to rub her head at a post-Golden Globe Awards party on Monday (16JAN06).

The CLOSER actress is sporting a short haircut after shaving off all her hair last year (05) for her latest film V For Vendetta.

After Theron's pal dared her to touch Portman's regrowth, the Oscar-winner couldn't resist.

Portman says, "Charlize and I have a mutual friend who dared her to come rub my head.

"My hair is growing very slowly because I am a vegetarian."
