Gary Barlow has a lot of famous friends and if reports are to be believed, he has picked up yet another in the Bee Gees star Robin Gibb.

The pair are said to have struck up a firm friendship over the past year and insiders have told The Mirror that the X Factor judge will be in the audience when Robin – who is suffering from liver cancer – performs at his charity comeback concert at the London Palladium on February 13.

Robin and Gary met last year when they and Robbie Williams met at the Butterfly Charity Ball in May.

Earlier this month, Robin was named as patron of the ‘Rock The House initiative,’ a charity that gives British musicians the chance to earn a living from their art by protecting copyright.

He is hoping to help raise over £50,000 for www.coming-home.org.uk at his concert next month, a charity which helps wounded soldiers back in the UK. The seriously ill singer will perform three songs and admitted:

“I’m looking forward to appearing if possible and being able to continue my support for our servicemen and women.”

A friend told The Daily Record:

“Quite simply, it is a miracle Robin is able to perform. He is still incredibly weak and sleeping up to 14 hours a day.

“Robin will be literally dragging himself out of bed to do this gig. He is passionate about the charity and wants to do his bit.”
