Will Smith Crashes J Balvin’s Coachella Set to Perform ‘Men in Black’

Will Smith made a rare appearance onstage this weekend — crashing Coachella to perform a song from the ’90s … and doing it alongside none other than J Balvin.

Indeed … very random, but no less entertaining. Balvin had an alien-themed design and aesthetic for his Coachella gig … and at one point in the set, he brought out WS who was rocking his signature ‘MIB’ ‘fit … only to rap the “Men in Black” song from the titular movie.

The crowd seemed to love it … and Will’s performance is getting rave reviews too, ’cause people could clearly hear his vocals as opposed to a backing track.

As for why Balvin brought out Will at all … anyone’s guess, but hey — it was cool. We know Will’s got a new ‘Bad Boys’ movie to promote, but this really doesn’t serve that purpose.

The Smiths were at Coachella as a family, it seems, ’cause Jada Pinkett-Smith was there too … as was Jaden Smith, whom we saw hanging out with Justin Bieber this weekend.  Their daughter Willow was performing at the festival … so makes sense the whole crew was there.
