Robbie Williams is planning to collaborate with his dad.

The 40-year-old singer, who invited his father Pete Conway to perform with him at London's Palladium in November, is set to work with him again.

According to The Sun newspaper, Pete said: ''I loved doing the Palladium with him. It was great. I really enjoyed it. We're going to do something together soon. It will be announced shortly - I just don't know all the details yet.''

Stars including Liam Payne from One Direction, singer Adele and comedian Alan Carr watched the pair duet at the show, which also saw the former Take That star perform songs from his album 'Swings Both Ways' and sing with Lily Allen.

Robbie and his dad sung 'Do Nothing Til You Hear It From Me', and Pete hugged his son before he left the stage to rapturous applause.

Meanwhile, Robbie ''doesn't want to upset'' bandmate Gary Barlow by saying no to a Take That reunion.

The 'Let Me Entertain You' hitmaker has reportedly suggested that they take things slow by working on material together - along with fellow bandmates Mark Owen, Jason Orange and Howard Donald - for now, and then discussing a world tour at a later date.

The source said: ''He's suggested recording together, seeing how that goes then embarking on a world tour in 2015.''
