But is Robbie Williams annoyed about it?
Pop star Rob, 41, just released his latest album, Heavy Entertainment Show, and has revealed he tried to get some A-List musicians to work on the new tracks with him.
However, everyone he called told him they were unavailable – but it looks like they were all up for working with a much younger star.
‘Last year I tried to work with Bruno Mars – didn’t hear anything back. Tried to work with (Swedish hitmaker) Max Martin – didn’t hear anything back. They literally didn’t return my calls,’ Rob told the Radio Times
‘Then I met Harry Styles in an airport. “Oh, you’re writing, Harry? Great, who with?” He goes: “Well, I just spent a week with Bruno Mars, and I’m about to spend a week with Max Martin”,’ the Rock DJ legend reveals.
However it sounds like Rob is far from jealous of the 22-year-old, telling him: ‘“You’re the new me. Good luck!”’
Harry – who will follow Zayn Malik and Niall Horan as fellow One Direction stars to release solo music – is expected to release his debut album next year.
The star will also be seen flexing his acting muscles with a role in Christoper Nolan’s war drama Dunkirk – due out in cinemas in July next year.
