Robert Downey Jr. On Drugs Again?

What a nice guy!

Actor Robert Downey Jr left presenter Lorraine Kelly lost for words by 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.

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

She welcomed Downey Jr 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 Kelly, 45, said "Thank you, that's nice," as Downey Jr added: "Particularly today."

Kelly 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."

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."

Downey Jr, 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.
