Oh dear, David Walliams, you just can’t stop being naughty, can you?

After he presented the GQ Awards last week, things went a bit quiet on Twitter for the comedian. It turns out that he went to Africa the day after for a Comic Relief project. He told his fans:

“I have just returned from a trip to Kenya with Sport Relief. This photo was taken at a centre for homeless children…”

It must have been rather quick, as he was back on Saturday to take part in Pup Aid at Primrose Hill, together with wife Lara Stone, Ricky Gervais and Ian Wright. Bert was the winner of coolest dog in London. It was an event to raise awareness about cruel puppy farming.

Meanwhile David got dissed on Twitter by non other then Rihanna last night, while he joked about her performance with Coldplay at the Paralympics Closing Ceremony.

He wrote:

“I bet Chris Martin got a stiffy when Rhianna stroked his face.”

Fans posted this to Rihanna –with one saying:

“Rih is clocking everyone next it will b David Walliams”

The ‘We Found Love’ singer simply replied “who dat?”, which was retweeted close to 600 times. David is yet to respond.

Walliams also managed to do an interview for the Evening Standard and get into trouble again, which is strange when you’re promoting a kids book about bullying.

The title of the interview was bound to cause controversy: “David Walliams: ‘Piers Morgan? He comes between farts and rats’”

The subject of the title was immediately riled when David tweeted a link to the interview, screeching:

“And yet he has 1.8m more followers than you, Dave.”

Lord Alan Sugar then got involved, saying:

”WHY ARE YOU BRAGGING AGAIN ABOUT FOLLOWERS IT SHOWS HOW INSECURE YOU ARE. Majority of your followers are mine “

David replied to Piers: “Are you tweeting from prison?” to which Piers said: “No, mate, from the River Thames – where your career ended up. Mwah. Do try and curb your jealousy @davidwalliams – it’s not my fault you’re less well known than Susan Boyle’s cat Pebbles in America.”

David hit back:

“Did you shag her cat as well or just Susan…?”

Piers replied: “that was SUCH a funny joke, Dave! What happened – gagwriter pull a sickie today?” What a dull comeback.”

Morgan appears in David’s upcoming book Ratburger on a long list of unloved things including slugs, worms and stinging nettles. He told the ES:

“He comes between farts and rats — which I think is unfair on rats. But I like to have one or two jokes for the parents reading to their kids. When I started writing I wanted to fill the books with references to TV shows and products. You realise though, as time passes, it really dates them, but my guess is that Piers Morgan will still be unloved for generations to come, so I think it was all right”.

In more “normal” news David revealed you can win tickets for his Ratburger premiere and he revealed Britain’s Got Talent will go to Scotland this year adding:

“Me & my Simon are coming to Scotland for #BGT! I’ll wear a kilt if you promise that you’ll audition. I’ll even bring Bert. Apply at http://talent.itv.com/”

Wait a minute? Didn’t they go to Scotland last year too?
