YMCS Barbie brings out Sean Kingston for his first stage performance since a near-fatal jet ski accident.

Fans attending Nicki Minaj's opening show for Britney Spears' "Femme Fatale" tour at Miami's American Airlines Arena were treated to two surprises, as she brought both Sean Kingston and Trina on stage.

The performance was Kingston's first since a near-fatal jet ski accident in May left the singer/rapper in critical condition. Kingston performed his single "Letting Go (Dutty Love)" on stage.

Trina also joined the party, as the Miami rapper spit her verse on the "My Chick Bad" remix. Minaj was on the original cut of the Ludacris track.
