Dame Emma Thompson has branded Meryl Streep "a very good snogger"

Speaking to BBC Radio 1 DJ's Alice Levine and Dev Griffin, she said: "Meryl Streep is a very good snogger - I had to snog her in 'Angels in America'.

"She was method about it can I just say...there was no stone unturned in my gob that's for sure...blimey what's she doing here, mining for jewels?"

The 60-year-old actress also recalled a "good kiss" with Robbie Coltrane in another drama series, 'Tutti Frutti', in 1987 but admitted the smooch wasn't painless.

She said: "Well, I did have a good kiss with Robbie Coltrane in 'Tutti Frutti' in Glasgow, but it turned into a bit of a tooth kiss you know where you just go, 'Ow, ow ow.' "

The 'Saving Mr. Banks' star also joked she wouldn't "recommend" becoming super rich because it can make someone "less of a human being".

She quipped: "You get rich by holding on to everything you ever, ever earn and never giving any of it away, and slowly becoming less of a human being, so I wouldn't recommend it."

And Emma - who has daughter Gaia with husband Greg Wise - admitted she used to steal sweets from her local shop when she was a child.

She confessed: "I mean when I was six...we didn't get pocket money. On Sundays we weren't allowed sugar, which was very good but of course turned me into a thief when I was young.

"So I started stealing sweets from the local sweetie shop. I used to take these gummy snake things, because they were in a low level shelf...and I used to take one of those and shove it up my sleeve."
