PHOTOS: Salman, Katrina 'back together'

Superstar Salman Khan is happy to be "back together" with actress Katrina Kaif to shoot a song for upcoming film "Tiger Zinda Hai", a sequel to 2012 blockbuster "Ek Tha Tiger". The "Sultan" star took to Twitter to share a glimpse from the shoot. He posted an image with him in tuxedo and Katrina -- with her locks falling over her shoulder -- in a gown. Salman captioned the photograph with Katrina -- his once rumoured ladylove: "Back together in 'Tiger Zinda Hai'". Yash Raj Films' "Tiger Zinda Hai" has been shooting in scenic locales of Tyrol, Austria, currently. The film's unit has wrapped up shooting in a historic and quaint Golden Roof for a song with Salman and Katrina.
