Cheeky Robert Downey Jr's Lorraine Quip

Oh-er! Lorraine and her cleavageCheeky Robert Downey Junior left TV presenter Lorraine Kelly lost for words after telling her: "Your tits look great!"

The former Hollywood bad boy had daytime viewers choking on their cornflakes when he made the remark on ITV1 show This Morning.

Lorraine, wearing an orange cardigan and black camisole which revealed a hint of cleavage, was hosting the show in place of Fern Britton.

She welcomed Robert to the show by telling him: "You look fantastic, you look really well."

The 40-year-old actor replied: "Thanks. I was going to say that your tits look great too!"

A clearly shocked Lorraine, 45, said: "Thank you, that's nice," as Downey Jr added: "Particularly today."

Robert Downey JuniorLorraine managed to say: "Oh good, well I'm glad I made you happy."

Gazing down at her cleavage and adjusting her top, she said: "I didn't realise they were so out."

Lorraine's co-host Jeremy Kyle, on his first day as temporary replacement for Phillip Schofield, stepped in to change the subject by saying: "Let's move swiftly on."

An embarrassed Lorraine agreed: "I think we should."

A This Morning insider said: "Lorraine wasn't showing acres of cleavage so his comment was a little unexpected. She was a bit embarrassed but carried on with the interview like a pro."

Robert, who earned an Oscar nomination for his role in Chaplin and won a Golden Globe for his guest spot in TV series Ally McBeal, is currently clean after a well-publicised battle against drug addiction which resulted in a spell in prison.

He landed a record deal after singing on Ally McBeal and is now launching his debut album, The Futurist.

He also has two films due for release - Disney remake The Shaggy Dog and action thriller Kiss Kiss Bang Bang with Val Kilmer.
