Mark Owen and his wife Emma were among the celebs out to watch and take part in Gary Barlow's 40th birthday concert at Shepherd's Bush Empire last night. Gary took to the stage with Mark and Chris Martin among others during the two hour concert, and guests including James Corden, Chris Moyles, Andrew Lloyd Webber, Lulu, Ellie Goulding, Kimberley Walsh and Take That's Jason Orange were part of the crowd. Robbie Williams appeared with a recorded message, and Gary cleared up yesterday's news stories about him seeing Take That as a four-piece, by saying he knows that Robbie is still interested in his solo career, but he loves working with the lads whether there's four or five of them. This isn't too surprising as when the band reunited they stated it was just for a tour and an album. All proceeds from GB40 went to charity, and the event was broadcast live on Radio 2 — you can listen again here.
