Robbie Williams' ‘prostitute’ admission leaves Julia Roberts completely speechless

Robbie Williams certainly doesn't do things by halves as he made quite the impact on The Graham Norton Show last night (10 October).

He was on the talk show sofa alongside Julia Roberts, Colin Farrell, Benedict Cumberbatch and Gloria Estevan to perform his song 'Pretty Face' ahead of the release of his upcoming album Britpop.

Robbie was the show's musical guest, and he rather swept in at the end to chat with the others, telling Roberts he'd seen her movie, Pretty Woman, 'six times in a row'.

Some Graham Norton Show viewers were a bit miffed that he nabbed the position of honour on the left of the sofa nearest to the titular host, making everyone budge up a bit, but there's not really a rule which demands the musical guest perch on the far end.

As for what he said when he parked his posterior on the sofa, it was something which left the Pretty Woman star speechless.

When he got the chance to sit down with the other guests, he was asked how many of them he knew, with Robbie saying he knew 'everybody from watching them on the telly', which got a laugh.

Turning his attention to the actor sat next to him, he then said that Pretty Woman and watching it so much had given him an idea of something he could do with a prostitute. Don't worry, it's nothing sordid, this is the BBC we're talking about.

He said: "Julia Roberts, oh my god, I can’t.

"I’ve watched Pretty Woman six times in a row. And at the end of the six times, I was like 'one day I will take a prostitute shopping'. And I did, I did. So, thank you."

Roberts didn't really know what to say to that, but fortunately, that's why talk shows have hosts, as Graham Norton stepped in to steer the conversation.

"That’s a lovely story Robbie. That’s really lovely," the host said as he got things back on track.

There's often a fun time to be had on Norton's sofa as a steady stream of celebrities come on to talk about their latest projects and spill some titbits of information for a spot of entertainment.

Cillian Murphy was on there recently to talk about the upcoming Peaky Blinders movie and his distaste for Tommy Shelby's haircut, saying 'it's not grown on me' before explaining why the character would have it like that.

They also recently had Taylor Swift on as she showed off her engagement ring.
