Comic Relief 2015: Stars support Red Nose Day telethon

While one Direction were unable to take part in Comic Relief's Red Nose Day live telethon the British band invited their grown-up counterparts to take their place.

No Direction, comprising comedians Jack Dee, Nick Helm, Patrick Kielty, Vic Reeves and Johnny Vegas took to the stage of the London Palladium, emulating the 1D stars as they performed their rendition of Best Song Ever.

Donning wigs and the trendy garb of their young counterparts, Jack Dee was transformed into Louis Tomlinson, while Nick Helm was a dead ringer for Zayn Malik. Patrick Kielty paid his tribute to Irish star Niall Horan, while Vic Reeves took on the role of teen idol Harry Styles. Johnny Vegas was a rather suspect Liam Payne.

In a pre-recorded video One Direction, who are currently on tour in South Asia with their One the Road Again Tour, introduced the band.

While the comic tribute act had certainly made some effort with their look, the vocal talent didn't quite live up to the world's biggest boy band.

As they struggled with the words, the singers may well have made a hash of the popular song, but it was all for a deserving cause and would have certainly contributed to raising a lot of money for Comic Relief.

Speaking before the live performance Jack Dee said: "I'm most looking forward to expressing myself through the medium of dance and music, and seeing the audience in a state of absolute astonishment at what we do."

Johnny Vegas was trending on Twitter as Directioners applauded the heartfelt effort.

Meanwhile, X Factor host Dermot O'Leary showed off his dancing prowess as he boogied for 24 hours straight raising a staggering £643,336 from his Day of Dance.

The 41-year-old completed his danceathon epic at 7.20pm on Friday after showing off his moves outside BBC Broadcasting House.

O'Leary received the support of some of his famous friends including Jamie Oliver, Lenny Henry, The One Show's Matt Baker and Alex Jones and Holly Willoughby, Blue, Strictly Come Dancing winner Caroline Flack and Pussycat Dolls' Ashley Roberts.

O'Leary, who is not known for his dance moves, explained how the idea for his Comic Relief challenge came about during a drunken night of partying.

"I was at a friend's birthday a few months ago and at 3am I just said, 'We've been dancing for a while - do you reckon I could dance for 24 hours?"' he told Digital Spy.

"And stupidly, rather than internalising that thought, I texted Comic Relief that night. And then they texted me back the next morning and said, 'Great - we're on.'"

The presenter raised a phenomenal £643,336, but revealed his dancing days are well and truly over.

Speaking earlier to BBC News, he said: "I'm never going to dance again in my whole life. I swear."

It was also a good night for David Walliams. While he recently announced that he had separated from his wife Lara Stone, Orlando Bloom put a smile back on his face as he puckered up all in the name of charity.

As Walliams attempted to beat the world record for the amount of kisses received in 30 seconds, the Hollywood heart-throb gladly obliged with a smooch.

After the kiss, Orlando said: "David's always been my ideal leading lady."

The marathon fundraiser also featured exclusive comic sketches with Cheryl Cole, Robbie Williams, Salman Rushdie and Russell brand vying for the title of national treasure, while Bond Star Daniel Craig poked fun at himself in a comic video.

Grammy award winners John Legend and Sam Smith also peformed the official Comic Releif song titled Lay Me Down.
