Robbie Williams has admitted that he shouldn't have released 'Rudebox' as a single.

The singer unveiled the track from the album of the same name in 2006 but it only managed to chart at No.4 in the UK, with The Sun calling it the "worst song ever".

When asked by Grazia about any life regrets, the 'Candy' man admitted that 'Rudebox' is certainly in contention. He said:

"I wish I hadn't released 'Rudebox' as the first single from the album of the same name - a different one would've been better. And many embarrassing gaffes have been committed to YouTube for eternity. But these days I concentrate on more important things than regrets."

Williams meanwhile also spoke about his talents - or lack of - as he admitted a love of "showing off". He said:

"I'm best at showing off! When it comes to that, I'm the best in the world. If I'm honest, I'm quite good at everything, but not brilliant at anything. I'm an alright singer, an alright dancer, and I play pool and football quite well. Although when it comes to academic stuff I'm terrible."
