The larger than life, (and larger than he was last year!) pop star Robbie Williams has split once more with his song writing partner Guy Chambers.

Some of Robbies best material was written in conjunction with Guy, think “Rock DJ”, “Feel”, “Millennium”, “Let Me Entertain You” and “Angels”, but the pair parted ways in 2002. Reports emerged that Robbie’s record company was demanding that Guy work exclusively with Robbie and no other artists.

The pair reunited last year, but have parted ways for a second time after Williams discovered that Guy was working with former bandmate, Gary Barlow on ITV drama, Britannia High.

A source told The Sun: “Robbie and Guy patched up their differences last year. They had been back in the studio trying to find the spark that produced Rob’s best material.

“They gave it a go but it didn’t work out – they had both moved on. But while they were working together in LA, Guy was asked to work as part of a team with Gary on a new TV show.

“He never mentioned it to Robbie. Rob heard Gary was in LA working and found out it was with Guy. He wasn’t best pleased when he heard.”
