Amber Heard impresses with rap

Amber Heard surprised revellers by knowing 'all the words' to a Salt-N-Pepa song at a recent party.

The actress took part in Montblanc's 24-Hour Plays initiative in New York City this week, which sees stars given just a day to come up with ideas for performances.

After the event she joined the after-party held at B.B. King Blues Club & Grill, where she impressed guests with her dance moves and lyric knowledge.

'[She was] dancing to Salt-N-Pepa, and knew all the words,' an insider laughed to New York Post.

Amber was spotted with Macaulay Culkin at the event and although she had fun she didn't want her evening interrupted. The 26-year-old star ' who is rumoured to be dating Johnny Depp ' reportedly didn't want to be pictured at the party.

'Amber didn't want anyone taking photos, and asked one of the people who managed to get one to [let her] see it. I guess she approved,' the insider explained.

Also at the bash were Olivia Wilde, Jason Biggs, Jeremy Renner, Vanessa Hudgens and Jason Sudeikis.

During her earlier stage performance, Amber caused a stir when she fell over mid-way through her skit. Although she composed herself quickly, The Hurt Locker actor Anthony Mackie couldn't help joking about the mishap.

'The [most fun] was watching Amber fall and almost kill herself,' he giggled. 'It was priceless.'
