Nicki Minaj has admitted she was stunned when Madonna gave her a birthday kiss during a video shoot last December.

The ‘Starships’ singer, who this week announced plans to launch her own fragrance, was on the set of the shoot for ‘Give Me All Your Luvin’ when the Material Girl planted a kiss on her lips just days before her 29th birthday.

Discussing the incident on The Graham Norton Show, Minaj said: "You can't really call it making out. She kissed me but I didn't kiss her. I wasn't expecting it and was shocked like everyone else. I was shaking and thinking, 'Is this really happening and why is she doing this?'”

The Trinidadian-born star, who alongside M.I.A. also appeared with Madonna at her half-time Superbowl show, continued: "It was the strangest thing, except she had very soft lips... I guess you could say that (she's a good kisser), but we didn't hang around in that lip locking thing. It wasn't all drawn out and crazy."
