Take That singer Gary Barlow celebrated his 40th birthday in style as he performed a special concert at London's Shepherd's Bush Empire last night (Thursday 20th).

The show was part of GB40, with all profits made going to charity.

The singer was joined by family and friends including Chris Martin, Ellie Goulding and Peter Kay as he sang tracks old and new, reports The Sun.

''Thank you so much for making my birthday so special'', Barlow told the audience.

Barlow will join the rest of his Take That band mates on a UK tour in the summer. For more details, check out Gigwise Gig Tickets.
