Bride Wars actor Kate Hudson panicked after shaving her head

London:  Actor Kate Hudson said she suddenly had a huge panic attack after she got her head shaved for a new project.

The 38-year-old actor, who got a buzz cut for her upcoming film with singer Sia, compared the big realisation to finding out the gender of a baby when its born, reported FemaleFirst.

"It's funny, too, because when (the cut) first started, I didn't think about it because it was for the role. It was like, 'Oh, let's do this!'

"I didn't think about it until it started. Oh! What is the shape of my head going to look like? I really started to panic. And all of the sudden it was like a birthing, like, 'It's a boy!' But 'It's round!'" Hudson told Jimmy Kimmel on his chat show.

The Deepwater Horizon actor previously revealed she loves the ease of having a clean head as compared to her long hair.

"I like the ease of it, you know what I mean? When I looked at the hair when it came off I was like you know this is... I'm so happy this is gone. It was a lot of wear and tear on that," Hudson had said.
