'Nobody liked my make-up!'; Uma Thurman

Actress Uma Thurman has hit back at claims that she has undergone plastic surgery, blaming her altered appearance during a recent red carpet event on an experimental make-up look.

During an interview with the Today show's Savannah Guthrie this morning, in which she was discussing her new NBC miniseries The Slap, the 44-year-old actress addressed recent speculation that she has had a cosmetic procedure done, labeling the rumors as 'nasty'.

'I guess nobody liked my make-up,' the Kill Bill star said when Savannah questioned her about the recent reports on her new look.

Uma, is that you? The 44-year-old actress sparked speculation that she has undergone cosmetic surgery, after she stepped out on the red carpet with a suspiciously smooth forehead

The mother-of-three went on to say that, while she didn't understand where the claims had come from, she refused to let them have an impact on her. 

'I've been doing this for years and years and years and people say things [that are] nice and they say things [that are] mean and it's like whatever!'

Uma first sparked worldwide speculation about her appearance after she stepped out at a premiere for The Slap with what critics described as a 'suspiciously smooth forehead' and an extremely tight smile.

Her comments about the reports on this morning's Today show follow a similar statement made by her make-up artist, Troy Surratt, yesterday, in which he also denied any claims that the actress has undergone cosmetic surgery, blaming her seemingly altered appearance at a recent red carpet event on an experimental make-up look.

Speaking to People.com, the cosmetics expert insisted that Uma was merely 'experimenting' with her beauty look, adding that he was 'surprised' by the scandalized reaction to it.

'By now I would have thought that we were all open to and knowledgeable of the role that makeup plays in the world of fashion and particularly celebrity, as a medium for creative self expression,' he said. 

'I think that women should feel open and free to experiment with different beauty looks — it's only makeup, at the end of the day it all washes off.'

When Uma debuted her new beauty look earlier this week, many critics were quick to compare her facial transformation to that of fellow Hollywood star Renee Zellweger, who caused quite the stir last year when she revealed her own drastically different look.

But Troy, who has also worked with the likes of Adriana Lima, Kristin Davis and Charlize Theron, insists that he and Uma had lengthy conversations about her altered make-up look prior to her red carpet appearance, with both deciding that it would be fun to do something unconventional with her cosmetics.

Explaining that he has grown tired 'of all the lash-y looks' that are so frequently worn by stars on the red carpet, Troy explained that he opted to focus Uma's look around a bold red lip.
