Robbie Williams is set to welcome a special guest for his upcoming UK tour - his dad.
Pete Conway, 64, will perform on stage with his superstar son throughout the tour to promote his album, Swings Both Ways, according to the Daily Mirror.
It's believed the father and son have been rehearsing a few different Frank Sinatra tracks to choose from for their duet.
The pair previously duetted together at the London Palladium and Pete recently hinted that they could be singing together again soon, saying: " 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."
Robbie, 40, also talked about what a great time they'd had at the Palladium: "I just loved being up there with Dad. Music has always been what connects us, well, that and family. So I was thrilled to see how much the audience loved him too.
"From being a kid, Dad's been my idol and I wouldn't have all this success if it wasn't for what I've learned from him."
Pete sang at Robbie's wedding to Ayda Fields in 2010 and the former Take That star returned the favour when his dad married Melanie Mills last May.
Robbie is set to play 17 UK dates in June and July before taking his tour to Australia.
