Lindsay Lohan presents her puffy “pillow face”

The 25-year-old troubled actress Lindsay Lohan appears to already be a big fan of cosmetic treatments.

Lindsay Lohan stepped out in New York ahead of her Saturday Night Live appearance, and showed off a very puffy “pillow face” – the term given to women who overuse facial fillers.

The young actress joins Madonna and Kylie Minogue as the most obvious examples of stars whose ever youthful glow suggests they may have had fat implants in their cheeks, causing the “pillow face effect”.

While Lindsay Lohan doesn’t appear to have gained weight, her face looked much rounder and the overall effect left her looking older than her 25 years.

Increasing numbers of celebrities are getting the plumped-up look, as opposed to the pinched back “wind tunnel” results of a face-lift or the “frozen” Botox look.

Lindsay Lohan stepped out ahead of the airing of a frank new interview with the Today show’s Matt Lauer in which she said she’s put the past behind her and is finally ready for a career comeback.

After a messy few years sprinkled with jail time, court appearances and house arrests, Lindsay Lohan swears she’s finally cleaned up her act and realizes she needs to prove herself.

In the interview, which will be screened in the U.S. on Thursday, Lindsay Lohan says: “I think that’s gonna take time…and I think that it’s actions.

“Because people can say things all they want, but I think I still need to go through the process of proving myself with SNL, being on time, being, you know, keeping my – can’t say the word – but stuff together.”

Linday Lohan certainly looked well put together in a sophisticated LBD and elegant heels.

She appeared alert and coherent in a bid to prove herself.

Lindsay Lohan says: “I don’t want people to have that reason to be scared anymore. So being able to have this opportunity with SNL and the film, I’m gonna do what I’m supposed to do, and enjoy doing it, and do it as best as I can.”

She also promises that she’s not going out anymore, and claims she’s actually morphed into a “homebody”.

“It’s not my thing anymore,” she says.

“I went out, actually, a few months ago with a friend. And I was so uncomfortable.

“Not because I felt tempted, just because it was just the same thing that it always was before. And it just wasn’t fun for me.

“I’ve become more of a homebody. And I like that.”

Lindsay Lohan also confirmed her plans to play Elizabeth Taylor in an upcoming biopic.

She reveals: “We’re in the middle of casting and figuring – we start production soon.

“I’ve been doing tons of research. But I’ve always kind of researched her. She’s always been a fascinating woman to me, so I’m really honored.

“And I will not let anyone down, especially myself.”

Lindsay Lohan is one court case away from putting the plethora of legal troubles she’s been plagued with since her 2007 arrest for drunk driving behind her.

The actress will host Saturday Night Live on March 3 for the fourth time and seemed excited today as she shot a promo for the hit NBC sketch show.
