Gary Barlow has revealed he doesn't see Robbie Williams as a full-time member of Take That.
The 40-year-old singer and songwriter is happy to have Robbie back with the band for their upcoming tour, but told Chris Evans' Radio 2 show, he only sees the reunion as a temporary arrangement.
Gary said: "I know we're back with Rob right now but we still see our future as a four-piece."
The singer is celebrating his 40th birthday this week by performing at a concert at the O2 Shepherds Bush Empire tonight (January 20), but he sees it as pleasure, not work.
He revealed: "My wife said 'What do you want to do on your birthday', and I said 'You know what - I want to play a concert because I love going on stage and singing'."
