Nicki Minaj got a superstar birthday greeting for her 29th this week when Madonna and M.I.A. sang 'Happy Birthday' to her.

Nicki, M.I.A. and Madonna were together filming the video for their new single 'Give Me All Your Love' so while they were recording one thing they took the opportunity to record another.
