Kat not allowed to wear bikini?

Its disappointing news for fans who wanted to see two bollywood hotties, Katrina and Hrithik together.  Its reported that Katrina had recently turned down Rakesh Roshan's offer to star in superhit Krrish's sequel.  Apparently Roshan Sr. was eager to have fresh pairing  opposite son Hrithik but Katrina cited date clashes with Karan Johar's Dostana sequel.

News is abuzz that the sequel requires the leading lady has to don a bikini and the  possesive boyfriend Salman has apparently placed a ban on Kat wearing a bikini. Hence Katrina refused the offer to uphold Salman's dictat.

However, Katrina' s loss turned out to be  Deepika Padukone gain who has happily taken up the offer to be cast opposite Hrithik.

Katrina and Salman's relationship has always been in the news either for break up or Salman's mercurial temperament, so wonder if this is just another rumour, or has some truth in it?
