Robbie Williams has run into his former Take That band-mates while recording his new solo album.
Williams' album, his first in three years, is being produced by 1980s production legend Trevor Horn in the same west London studio complex where Take That are recording.
"They're all in the building. Gary [Barlow] is in one of the rooms and Robbie's there, so they bump into each other and they get on brilliantly well," Horn told the BBBC.
Williams said this week that rejoining Take That - who have smashed album and ticket sales records since their reunion as a four-piece in 2004 - would be "fun".
"I'm in regular contact with them and it's looking more likely by the week," he told the Daily Mirror newspaper.
"The lads all seem up for it."
It is believed the Angels star could take the stage alongside Barlow, Mark Owen, Jason Orange and Howard Donald for a one-off appearance during the band's summer stadium tour.
However, his spokesman said the singer was not intending to take part in a tour or recording new material with Take That.
"He is fully focused on getting [his solo] album together and there are no plans for a Take That reunion," the spokesman added.
Williams' next album, which features songs written with Mark Ronson and Williams' former writing partner Guy Chambers, is due for release in the autumn and is likely to be his last album for EMI.
