There is a serious heat wave is blanketing the country right now, but it was hottest in Miami last night, as Nicki Minaj got not one, but two assists on her current Femme Fatale tour.

Local (and recovering) hero Sean Kingston, who suffered a life-threatening jet ski accident over the Memorial Day holiday, hopped on stage with the human Barbie doll for 'Letting Go (Dutty Love).' It was the first time Kingston has taken the stage since his accident. While local stars heading down to a big show and getting on stage to perform is a commonplace event in the pop music world, this particular performance resonated a little deeper, since it was like a little happy ending to what could have been a tragic story for Kingston.

But Kingston wasn't the only cameo of the night. Another local, 'Da Baddest Bitch' known as singer Trina, also joined Minaj for 'My Chick Bad,' giving the crowd a double dose of femme fatale power. The only thing missing was a little help from tour headliner Britney Spears. It was a sassy duet that certainly raised the temperature and estrogen levels in Miami a few notches. And no matter how much you shelled out for tickets, you got an extra special something thanks to two guest appearances!

Seeing Trina perform with Minaj got us thinking. Wouldn't it be rad if Minaj and nemesis Lil Kim buried the hatchet and performed on stage together one day? We know, it's a pipe dream!
