Kate Bosworth Sang 'Grease' Hits with Original Danny Zuko Himself John Travolta!

Kate Bosworth grabs a cup of coffee all bundled up before heading to the set of her new movie Life on the Line on Sunday (October 26) in Vancouver, Canada.

That same day, the 31-year-old actress tweeted some amazing news involving her Life on the Line co-star John Travolta.

“Spontaneous duet today with John Travolta singing “The One That I Want” & “Summer Lovin’” – dreams made.” she wrote on her Twitter page – John was the original Danny in Grease back in the 1978 film and sang both of those songs in the movie. We wish there was a video!

FYI: Kate is wearing a Banana Republic Furry Coat and Coach boots.
