Cher wants to star in Johnny Knoxville comedy 'The Drop Out'.

The singer-and-actress - who will soon be seen in 'Burlesque' alongside Christina Aguilera - has confirmed the project is likely to still be made following casting rumours in 2009, noting it is one of only two scripts alongside 'Mamma Mia!' she has been interested in.

Talking about the project, Cher - who would play the neighbour of a 30-year-old slacker who is kicked out of his home by his parents - said: "It's very dumb, very 14-year-old boy humour. I love it."

She also confirmed while at a round-table discussion for 'Burlesque' she could not star in 'Mamma Mia!', which starred Meryl Streep, Amanda Seyfried and Dominic Cooper, because of her hectic tour schedule.

Cher - who won an Academy Award for Best Actress in 1988 for the movie 'Moonstruck' - has only starred in two movies in the last 11 years, 1999's 'Tea with Mussolini' and 'Stuck On You' in 2003.
