Christina Aguilera has accused the likes of Britney Spears and Lindsay Lohan for their lack of self-control which could help them avoid drugs and alcohol.

The 26-year old singer claimed that the stars led wild lifestyles and showed little regard for the effects of their behavior on their career.

The ‘Beautiful’ hitmaker told Glamour magazine that when a person is 20 or 21 years old there is no boundary and it is then when the limits have to be set.

“When you hit 20 or 21 and you’re around drugs and alcohol, everyone has a moment when they like to dabble in it and express themselves,” she told the magazine.

“It’s called being young but there is a boundary. You see all of these horror stories about people that have died of drug overdoses, people that have taken it too far and ruined their lives, and for me, I had so many things that I had yet to accomplish,” she said.

“It was just a matter of thinking, I don’t want to waste any time, and sticking to the plan,” she added.

Aguilera’s also said that Spears should have stayed in the night before her MTV Video Music Awards performance to ensure her comeback was a success.

“Everyone has their own ways of choosing what’s best for them. I have no problem with telling someone, ‘Hey, I have to do a show tomorrow. I want to do a good job and be on my game’.

“Sometimes I wish I could go out to a party or a club and just be able to be free, but there’s a consequence with the temptation. You know you’ll feel it the next day when you wake up. There are too many things I have to accomplish,” she said.

Natalie Portman has vowed that she will never strip again for screen after filming a risqué scene for her new short movie “Hotel Chevalier”.

Portman’s nude shots will soon be available on the Internet even before the film is officially released. And she is upset that she agreed to do something that was awkward in the prelude to “The Darjeeling Limited” directed by Wes Anderson, contactmusic.com reports.

Portman has insisted that she was convinced that nude scenes were required for the movie.

Portman, who requested director Mike Nichols to cut the nudity from “Closer” and used a body double for “Goya’s Ghosts’, said that she felt it was right to do bare scenes in the latest film.

She said, “I don’t know why, exactly. Sometimes you make rules for yourself and sometimes those rules are made to be broken. You have to test things out and see what works for you, and this felt right.

“I’m really sorry I didn’t listen to my intuition. From now on, I’m going to trust my gut more. Sometimes the most powerful thing you can do is to say no.”

The Academy-award nominated star also said that she urged director Wes Anderson to give her a chance to work with him.

“I begged Wes to work with me and show me a script. I really loved it. He has the finest taste possible,” she said.
