The singer reportedly wants to disappear back to LA after the Take That tour this summer, and concentrate on starting a family with wife Ayda Field.
A source told the News of the World the Angels singer has already started building a nursery.
'Rob and Ayda always planned to start a family around a year after they married. He's loved being back with the boys but he's also keen to step back into his incognito LA life again,” the insider said.
'Rob wants to be a hands-on dad and has discussed this in depth with his Take That mates, particularly Gary [Barlow]. Gary is behind Rob all the way and always knew he wanted to return to LA and work on his family with Ayda. At the moment they're keeping schtum about whether they're actually expecting but it's telling that they are working on the nursery. We know they've been trying. The nursery is in its early stages but is filled with goodies from Hollywood boutiques.'
A spokesman for Take That said: 'They have new single Kidz out on February 13 and they are very happy continuing to promote their current album. They are even writing new material as a five-piece.'
