(Cover) - EN Showbiz - Natalie Portman feels she has an immature attitude to sex scenes.

The 29-year-old actress has shot a series of intimate love scenes during her Hollywood career, and her role in new romantic comedy No Strings Attached provides no exception.

The brunette beauty plays Emma Kurtzman in the movie - which also stars Ashton Kutcher - about a guy and a girl who try to keep their relationship strictly physical.

Natalie feels she didnt cope too badly with shooting the intimate scenes, but was keen to make sure she appeared in a good light.

"I'm pretty immature," she is quoted as saying. "I get pretty embarrassed easily. For this movie I made a point of checking certain shots to make sure that I felt OK. There was one of the panties coming off that we did and after I watched I was like, 'Oh, that's not bad,' because it was really quick and it wasn't lingering on anything that I felt modest about.

The talented star finds it amusing how actors are required to make small talk in between the filming of romantic sequences. Natalie always tries to discuss something light-hearted with her leading men in a bid to reduce tension.

Then you go the opposite direction between takes, like, 'So, what are you doing this weekend?' Like totally benign conversation between to make it a little normal. (C) Cover Media
