The cast of Broadway musical "Hairspray" got a big surprise after they finished last Friday's show and walked off stage to find Tom Cruise and his wife, Katie Holmes, waiting in the wings.

The Hollywood couple attended the stage version of the hit show with their 2-year-old daughter Suri and were granted a backstage visit afterwards to meet the actors.

But the cast had not been informed of the stars' visit and were shocked to be greeted by the family after the performance.

Jenifer Lewis, who plays Motormouth Maybelle in the hit show, was delighted to meet Cruise and Holmes.

She tells New York Daily News, "I turned, and there was Tom Cruise saying to me, 'Oh my God, you're wonderful!'

"Suri was so sweet in her little velvet and taffeta dress."

Cruise later sent the whole cast flowers and a large basket of candy in time for their next performance.
