R&B stunner Cassie Ventura regrets not taking more acting classes before starring in Step Up 2: The Streets - because her performance was "a mess".

The singer jumped at the chance to score her first major movie role in the film, but now wishes she had waited for a part she could have been better prepared for.

She says, "I don't think I took enough classes. Reacting to five other people is completely different than being with an acting coach."

And she recalls the embarrassment of almost maiming a co-star when the task of driving and remembering her lines left her more than a little confused.

She tells Complex magazine, "I'm a horrible driver and my first day on set, I had to drive a car and act at the same time. I was thinking about too many things at once... I almost ran over the girl that I was talking to. It was just a mess." (c) WENN
