The singer, who has been a bit of a bachelor throughout his career, was on Sydney 2Day FM on the Kyle and Jackie O Show last week with Ayda Field (the girlfriend in question) when he reportedly popped the question.
He said: "Will you marry me? I love you so much, would you mind being my betrothed until the end of time?" and she replied: "I would love to be your betrothed until the end of time."
However, before you get too excited at the idea of an A-list celebrity wedding, the proposal has been written off by Robbie’s spokesman. He claimed it was just a joke. Despite this, Robbie’s mum Jan is adamant it was a genuine engagement. In a radio interview, she said: "He wanted to do something different. She's a lovely girl and I'm really pleased for them. I've got a daughter-in-law."
We wait with baited breath for the truth. Is Robbie finally going to be united in holy matrimony?
