John Travolta is the surprise secret star of Pitbull's new music video

One would assume that the bald fella in the new Pitbull video is, well, Pitbull.

But fans of 'Mr Worldwide' are being played all along, as a suited gentleman with a bald head and loafers with no socks ogles a series of gyrating women.

As the clip for Pitbull's new single 3 To Tango enters its climactic final act, the suited gent in the seat stands up, and we discover that it was none other than... John Travolta all along.

He then joins three ladies to show off his tango skills.

It's not all as random as it seems – Travolta and the Miami-born rapper are, for some reason, pals.

The Pulp Fiction star said back in February: “A good friend, Armando Perez, Pitbull, he lives his life like this.

“He would send pictures of me, I have all my hair, and he'd superimpose no hair and say, 'I prefer this,' so I thought... Maybe it's time to do it.”

Pictures of Travolta from a New Year party with his daughter, in which he revealed his new look, soon went viral.

“The only other time I was a leading story was when I mispronounced at the Oscars,” he added (as no one can forget, he introduced the Frozen star Idina Menzel as 'Adele Dazeem').

Pitbull backs up the story too.

He told Jimmy Fallon: “He gave me an award at the Chinese Theater in Hollywood, so when I was there, he said 'Hey man, I like the look with the shaved head and the beard. Is it cool if I do that?'”

And the rest is history.
