Gwyneth Paltrow: Sexy teacher on 'Glee'

There have been many celebrities who have graced the halls of William McKinley High as guest stars in hit US TV show Glee.

And among the most highly-anticipated celebrity performers on the programme includes Gwyneth Paltrow.

In a new clip from the episode, due to air in America on Tuesday night, the 38-year-old actress is seen wearing a sexy mini-kilt and black knee-high boots as she belts out Cee Lo's Forget You.

Paltrow plays substitute teacher Holly Holiday, who comes into the school when Matthew Morrison's character Will Schuester gets sick with 'monkey flu'.

Singing is something of a new foray for Paltrow, who also performed live at the Country Music Awards earlier this month to sing Country Strong, the title track from her upcoming movie.

And, as well as earning a standing ovation from the audience at the awards, Gwyneth's performance went down incredibly well with her Glee co-stars.

The show's creator Ryan Murphy said: 'She loved it, actually. She's just the best. She's the easiest, breeziest girl around - she's such a professional. She was so prepared, she worked so hard.'

American singer Cee Lo added he was 'flattered' to have had his hit track performed by an Oscar-winning actress on such a popular show.

He said: 'I really am just flattered that not only Glee [covered it, but it was Gwyneth singing.

'I didn't realize when we first did the clearances for it. I just thought that maybe it would be sung by the cast, but it turns out to be her. I'm like, "That's just, that's too awesome."

But while Gwyneth has wowed fans with her singing voice, she admits taking on a film role which required her to perform was daunting.

However, luckily for her, she was able to call on some of her more famous friends for advice.

Gwyneth said: 'I asked Faith Hill a lot of questions ... and Beyonce actually too. I studied Beyoncé a lot and her concerts for her kind of confidence.'

As well as performing Forget You, Gwyneth also sings a mash-up of Rihanna's Umbrella and Singin' In The Rain.

Jane Lynch, who plays cheerleading coach Sue Sylvester in the show, said: 'Gwyneth Paltrow is the substitute and the kids all start to love her, so there's kind of a rivalry between Sue and Gwyneth's character.

'She's got the goods. She can sing, she can dance. I really was [blown away]. I saw them doing a mash up of Singin' in the Rain and Umbrella.

'They are singing and dancing their hearts out and Gwyneth is leading them. She's amazing.'

Mila Kunis: Black Swan Sexy

Mila Kunis looks stunning at the Black Swan closing night gala during AFI FEST 2010 at Grauman’s Chinese Theatre in Hollywood on Thursday (November 11).

The 27-year-old actress wore a black silk crinkle chiffon and grosgrain bow dress from Oscar de la Renta.

Mila had to film a love scene with Natalie Portman for the film, which she found very difficult to do because of their friendship. “It is slightly uncomfortable to have to be intimate with a good friend. The scene’s important for the character, but we went in going, ‘This is going to be a little different,’ yeah,” she told Virgin Media.

“We shot everything both ways. Sometimes I would be the sweet one and Natalie would be the mean one, and then we’d flip it. At the end of the day it was all up to Darren [Afronsky]
