Robbie Williams is planning to collaborate with his dad.
The 40-year-old singer performed with dad Pete Conway at London's Palladium in November and wants to work with him again.
William's father says he would welcome the opportunity.
"I loved doing the Palladium with him, it was great," Conway told The Sun newspaper.
"I really enjoyed it. We're going to do something together soon ... I just don't know all the details yet."
Liam Payne from One Direction, singer Adele and comedian Alan Carr were in London to watch the pair sing Do Nothing Til You Hear It From Me, with Conway leaving the stage to rapturous applause.
Williams also sung with Lily Allen in between songs from his new album Swings Both Ways.
The former Take That star is also not ruling out a reunion with the boy band because he "doesn't want to upset" bandmate Gary Barlow by saying no.
Williams has reportedly suggested that they take things slow by first working on material with former bandmates Mark Owen, Jason Orange and Howard Donald, and then perhaps discuss a world tour at a later date.
