She's one of the most attractive British journalists on our screen who always look chic and smart as she delivers us the daily news.

But last night, Katie Derham ditched the suits and the serious disposition for smiles and Hollywood glamour as she took to the stage in the name of charity.

Katie, 41, looked sensational in a long red sequinned dress as she strutted her stuff for Newsroom's Got Talent.

The annual charity event sees all new teams from the major channels compete against each other as they perform musical numbers at the event, which this year raised money for Beating Bowel Cancer and Leonard Cheshire Disability.

Katie used to present London Tonight and anchored the ITV lunchtime news but left ITN last year to join the BBC.

But she teamed up with her former colleagues, including sports correspondent Steve Scott, to perform their version of Singing In The Rain, before they launched into a rendition of It's Raining Men.

She said: 'I left ITV News a year ago, so it was great to feel part of the team again. Tonight was the first time we had all managed to get together to perform and the first time I had actually been lifted up on stage.

'It was fantastic to raise money for such good causes and to support Leonard Cheshire Disability, who I first got involved with three years ago.'

But despite the standing ovation from the celebrity judges Arlene Phillips, Christopher Biggins and Anton Du Beke, it wasn't to be their night.

The winners: Led by Faye Barker, the London Tonight team performed Cell Block Tango from Chicago

Because the performance of the night that won the Newsroom's Got Talent crown came from the London Tonight team, who performed Cell Block Tango from the musical Chicago.
Led by London Today presenter Faye Barker, the girls from the team donned short black dresses, black tights and heels as they sang the song, which went down a storm with the judges, with Arlene calling the performance 'reem'.
And the former Strictly Come Dancing judge took to her Twitter to congratulate them and added: 'Sensational wit sharp choreography and talented performances.'

Barker said: 'It’s amazing to have won. Everyone tonight was brilliant. We rehearsed late at night but our performance didn’t really come together until this evening. The competition was really tough this year so we were really thrilled to have won.'

The Sky News girls also wowed the judges on the night as Charlotte Hawkins, Nazaneen Ghaffar, Sarah-Jane Mee, Jacquie Beltrao and Sarah Hewson performed the Girls Aloud song The Promise.

Hosted by comedian Brian Conley and Loose Women presenter Carol Vorderman, the night also saw performances from Jon Snow, Cathy Newman and Krishnan Guru Murphy who performed Build Me Up Buttercup.

Snow said: 'It was exhilarating. I can't remember the last time I was so nervous. We rehearsed every lunch time for the last week, and I think tonight we got it absolutely right. It was a great way to help celebrate Channel 4’s 29th birthday and we’ve all had a lot of fun putting the song together.'

Unfortunately, the Al Jazeera team, new contenders to the crown this year, left the judges cold with their rendition of Queen's Somebody To Love, which left Arlene moaning: 'Can anybody find me somebody who can sing?'

Kate Garraway and Dan Lobb, who was recently voted off Strictly Come Dancing performed Guns 'n' Roses's Sweet Child of Mine.
