Robbie Williams to rejoin Take That

Robbie Williams will rejoin Take That tomorrow night.

The singer - who left the band in 1995 - has agreed to perform with former bandmates Gary Barlow, Mark Owen, Howard Donald and Jason Orange for a charity show at London's Royal Albert Hall.

"The reunion is go. Robbie is utterly thrilled about it," a source told The Sun newspaper. "He has been dreaming of performing again with Take That for years and now it's going to happen."

As the stars reunite on stage for the first time in almost 15 years, Sir Paul McCartney is also expected to perform alongside them. The source added: "Gary has spent months organising the event. He is looking forward to singing with Robbie again, but landing Paul McCartney is without doubt his biggest coup. They haven't decided what they are going to sing together, but something will take shape in rehearsals today."

Robbie left the band following a series of heated rows with Gary, but the pair have since patched up their differences. Earlier this week, the 35-year-old star said he would love to perform with his former bandmates again. "I wouldn't want to go on a massive tour, but I would like to do something with the lads for fun," Robbie revealed. "I have only fond memories from being in Take That. I remember that I travelled around the world with four of my best friends and had girls screaming at us."

Other acts set to appear at the event, which will raise money for charity Children In Need, include Leona Lewis, Cheryl Cole, Dizzee Rascal and Snow Patrol.
