The funnywoman took a break from her movie career to raise her two young daughters Maude, 11, and Iris, six, with director husband Judd Apatow.
But before she threw herself back into acting, she decided to take a refresher course to hone her talents - and found herself practising her skills with the hip-hop star, real name Tariq Trotter.
Mann says, "I took a bit of time off to raise my kids and wanted to freshen up my acting skills so I took an acting class and Tariq was my acting partner. He was really good, he's a really good actor. Danny and the Deep Blue Sea, just a play that we did. I remember he was being very nice and polite.".
