The former Fugees frontman celebrated the milestone by posting the bonkers picture on Twitter.
He accompanied the ripped snap with the caption: “TODAY I AM 43 YEARS OLD! I look And feel 26! U cant keep ‡ good Man down! Keep ‡ smile when they want you to frown!”
His skimpy red and blue pants matched the colour of his Ducati motorcycle - a red, white and blue ride complete with American flag.
Many of his near 3million followers were soon hailing the ‘Haitian sensation’ on the social network.
And the now solo singing star took time out to retweet some of his favourites.
One from a female fan read: @wyclef they can say what they want... But at 43 you look damn good on that bike!!!”
Another wrote: “I applaud @wyclef for posing in the speedo ! His body looks great.”
