Me+ U singer Cassie credits Sean Combs with her new-found confidence on stage, insisting she'll never care what others think of her again. The shy star recently admitted her live performances have been lacklustre and claims she was too self-conscious to feel comfortable singing in front of crowds. She tells Rap-Up magazine, "I would hold back a lot 'cause I didn't want to look or feel weird around people, but he taught me to let go." The 19-year-old also reveals that Oscar winner Jamie Foxx is the most famous name in her cell phone adding, "I didn't even ask for his number. He gave it to me!"
