The event was launched by funnyman John Cleese in the 1970s, bringing together a star-studded mix of comedians and musicians to raise money for charity and highlight the importance of freedom of speech.
After a four-year absence, the traditionally British-held ball took place in America for the first time on Sunday night (04Mar12) with a show at New York's Radio City Music Hall.
British and American comedians took it in turns to grace the stage, while Stiller and Walliams teamed up for a joint performance to discuss language discrepancies between the U.K. and U.S., with both agreeing the word "Bush" was "embarrassing" for both nations, but "Piers Morgan" translates as "annoying" on both sides of the Atlantic.
The evening also included musical performances from Mumford & Sons and Coldplay, whose frontman Chris Martin told the crowd as he took to the stage, "We take pleasure in being the least funny act here."
The event raised money for Amnesty International.
The Little Britain funnyman was planning to fly to New York to discuss a joint adventure with his TV star pal Bear Grylls but his Dutch partner Lara Stone put a stop to their plan to go rock-climbing together.
Walliams tells Britain's Radio Times, "It was only scaling a rock face, but Lara got really upset and said no."
The comic admits the blonde beauty, who he married in 2010, became an emotional wreck as she cheered him on during his marathon river swim, which left him with severe back problems and a stomach bug.
He adds, "I didn't like to see her upset, but it was great having her support. She actually had her driving test on the day I got ill, so she heard it on the radio and was doubly upset she hadn't been there to look after me."
The Little Britain star is adapting his second book Mr Stink into a 60-minute programme for the BBC.
The novel, about a 12-year-old girl who meets a tramp and helps look after him, was recently nominated for a top literacy award in the U.K., and Walliams is delighted his tale will hit screens later this year (12).
He says, "I am beyond thrilled that BBC One is adapting my children's book Mr Stink into a family film. I have written the script, and can't wait to see actors bring it to life."
Carmen Electra will step in to cover British TV presenter/actress Amanda Holden on the judging panel of Britain's Got Talent this week (begs06Feb12). Holden is taking time off from the show following the traumatic birth of her second daughter last month (Jan12) and Electra will take her place - alongside Simon Cowell, David Walliams and Alesha Dixon - at the London round of auditions from Monday (06Feb12).
Funnyman David Walliams has been tipped for a top literacy award in his native U.K. - his book Mr Stink is in the running for the title of best children's novel of the last decade. The Little Britain star will go up against authors including J.K. Rowling, whose book Harry Potter And The Order Of The Phoenix was also named on the shortlist. The winner will be announced next month (Mar11).
The Britain's Got Talent judge delivered Hollie Rose last Monday (23Jan12), but a complication left the new mum in a critical condition and her representative only confirmed the tot's arrival on Wednesday (25Jan12).
Holden's celebrity friends, including Simon Cowell and David Walliams, reached out to the star as she recuperated, and now she has been allowed home to enjoy being a mum to baby Hollie, as well as her eldest daughter Lexi.
Her spokeswoman Alison Griffin says, "We are delighted to say that Amanda is now home. She and (husband) Chris would like to thank everyone who was involved in her care for their amazing skill and dedication, and also to thank everyone who sent such kind thoughts and wishes during this time.
"She is, of course, thrilled to be home with her family - Hollie is absolutely beautiful and Amanda and Chris are completely besotted with their two girls."
The Little Britain star is busy working on his first memoir, entitled Camp David, for release later this year (12), and the 40 year old is enjoying recalling experiences from throughout his life.
He tells BBC's Newsbeat, "It's weird, in writing it you remember more and more things. Also, it's good to ask other people what their memories are.
"I did keep diaries from about the age of 30, so I've got a lot of stuff there. I think the hardest thing is recalling people's names - like a teacher who taught you 30 years ago."
The Britain's Got Talent judge delivered Hollie Rose on Monday (23Jan12), but a complication left the new mum in a critical condition for three days.
Her representative confirmed the birth on Wednesday (25Jan12), when doctors finally pronounced Holden out of danger - and her celebrity pals have reached out to the star to give her their well-wishes as she recovers in hospital.
In a post on his Twitter.com page, Cowell writes, "Congratulations, thrilled for Amanda Holden", while Morgan adds, "So happy for Amanda Holden & (husband) Chris on the birth of Hollie Rose."
Walliams reveals his fellow Britain's Got Talent judges - Cowell and Alesha Dixon - were terrified when they learned Holden had been taken ill following the birth.
He says, "It's fantastic news, we were all worried when we were doing the show after hearing she was in hospital. We heard she hasn't been well, but I don't know more than that."
