Robbie Williams has admitted that he regrets going to rehab and having a fling with Geri Halliwell.
The cheeky former Take That star shared his thoughts on the mistakes he'd made in life as he performed at the London Palladium last night.
He said: "For a long time, as long as I can remember, I've felt a little bit stupid. I left school without any GCSEs, nothing higher than a D.
"I'm the first to admit I've made a couple of mistakes."
And as well as the rehab (or perhaps the problems that took him there) and the Ginger Spice, he also admitted that Rudebox was not his finest hour.
"Two trips to rehab. Rudebox the album. Geri Halliwell," he listed. "I should have gone for Victoria really, shouldn't I? I'd have been really famous."
But he then appeared to think better of his remarks, adding: "Sorry Geri Halliwell."
Robbie and Geri famously enjoyed a fling together in 2000.
