Actress bust some moves with the singer
The actress was shoeless and a bit tipsy at the time.
‘She didn’t speak to me or say hello,’ Maggie told GMTV.
‘But she did dance with me for about a minute and a half.
‘Someone introduced me to her and she kind of nodded at me and then started dancing.’
Maggie, 32, who stars in Nanny McPhee And The Big Bang, says it was a memorable moment.
‘It was everything an Oscar night should be,’ she added. ‘This is not something I do every day.’
