He’s back! Jamaican-American singer Sean Kingston set foot on a stage for the first time after his jet ski incident in May during Nicki Minaj’s live set at the ‘Femme Fatale’ tour pre-show in Miami this week – The raptress from Trinidad and Tobago invited his dear friend, now fully recovered from his injuries (fractured wrist and broken jaw), to hit the stage at Miami’s American Airlines Arena to sing together their 2010 summer hit “Letting Go (Dutty Love)”.
