We bet while Liam Gallagher was travelling the world with Oasis in the heady 1990s, he didn't expect to appear on a dodgy singing contest with Jessie J, Tom Jones and that bloke from The Script. Ok, so he's not auditioning, but his band Beady Eye will take to the BBC stage on Saturday night (May 15, 2013) to sing live on 'The Voice.'

There is a problem.

Liam's sort-of arch-nemesis Robbie Williams - who isn't really his arch-nemesis - will also be on-set to record a pre-recorded performance with Dizzee Rascal. Heads will roll! Probably. Worried bosses are the BBC are apparently keen to keep both parties on separate sides of Pinewood Studios, despite the fact that Liam, nor Robbie are that bothered. A show source told The Sun: "Relations between Robbie and Liam do seem to have become less hostile but the bosses aren't taking any chances.They had hoped they wouldn't be in the studio at the same time but as Robbie's tour clashed with the final, his performance has to be pre-recorded. So we have given them separate Winnebagos on either side of the studio and called in extra security to be on hand in case the pair do kick off."

Robbie challenged Liam to a televised fight at the Brit awards in 2000, though they were headier times. Both stars were enjoying themselves - shall we say. But Liam did marry Robbie's ex-girlfriend Nicole Appleton.
