Jennifer Hudson gave her Sex And The City: THE MOVIE co-stars a treat on set - she serenaded the cast and crew in between takes.
Actress Cynthia Nixon admits her co-stars would burst into impromptu sing-a-longs to pass the time during takes.
But Sarah Jessica Parker, Kristin Davis and Kim Cattrall were awestruck when Hudson came on board for a featured role in the 2008 blockbuster - because they were blown away by her powerful vocals.
Nixon says, "You get pretty punch drunk at that point. We sing a lot of show tunes... it was so amazing when we did the film we had Jennifer Hudson on the set and sometimes she would sing for us. That was a treat."
