Kate Bosworth Sang "Grease" Hits With John Travolta

Kate Bosworth recently announced on twitter some really exciting news about 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," Bosworth, 31, tweeted on Sunday.

Bosworth, though, didn't mention if there is a clip of the two singing the "Grease" hits…
