50 Cent Surprises Crowd at Yacht Party, Sprays Champagne Onstage

If the boat’s a-rockin’, ya gotta come a-knockin’ … ’cause it might just be 50 Cent whipping the crowd into a frenzy onboard!

TMZ has obtained video of the rapper surprising a ship full of people Friday night … after Flo Rida brought him out as a special guest during a performance at a party hosted by Houston Rockets governor Tilman Fertitta‘s.

Check out the video … Flo gives his longtime friend a wonderful intro — calling him one of the greatest rappers ever — before 50 struts out and drives the crowd wild.

50 Cent starts with his song “P.I.M.P” before moving on to other classics like “Candy Shop” … with Flo Rida hyping everyone up beside him.

At one point, we’re told the stars sprayed a bunch of champagne onstage … and, it wasn’t the cheap stuff either — they showered Le Chemin du Roi from 50’s Sire Spirits on the stage.

The event 50 surprised fans at was Fertitta’s Salute to San Luis in Galveston, Texas … an annual Mardi Gras event. Fertitta was recently named the Ambassador to San Marino, a microstate near Italy, by President Donald Trump.
