Last night we saw an obese John Travolta dressed as a woman.
Boobs 'n' all, he was shaking his booty and having a good old sing-song.
All of this was on the big screen, of course, for John's role as Edna Turnblad in the new movie musical, Hairspray.
Newbies Amanda Bynes, Zac Efron, Elijah Kelley and Nikki Blonsky were all stoked to have worked with such a megastar.
We couldn't resist rolling up to the world premiere in Leicester Square to see how John cuts it as a lady.
So we skipped off down the massively multi-coloured carpet to have some chats with the cast, along with the celebs who managed to bag a ticket.
Check out who said what and all the outfits in our gallery.
