One of the hottest pairs in Bollywood, Salman Khan and Katrina Kaif seem to be heading for splitsville. They have been having many fights of late especially with regard to their respective co-stars Asin and Ranbir Kapoor.

Says a source in B-Town, “Salman and Katrina have been having problems for over a month. Though their relationship has hit rough spots before, and they’ve taken a break from each other, it remains to be seen if this time the split is final.

The couple has been having arguments for some time now but things came to a head about 20 days ago. The couple had a major fight over various issues the main one being Katrina’s growing proximity to her Ajab Prem Ki Gajab Kahani (APKGK) co-star Ranbir Kapoor.”

A friend close to the actor says, “Initially, Salman didn’t pay heed to the Kat-Ranbir rumours. Especially as the actress told him that the Kapoor boy had a crush on her and she wasn’t interested in him. But stories carried back by the unit of (APKGK) from Ooty, confirmed his suspicions.

“When Salman confronted his girlfriend, she turned around and told him that she didn’t question him about his link-up with Asin, so had no business asking her about her friendship with her co-stars.” Sources also reveal that Salman (43) has been wanting to get married and have kids, while Katrina (24) feels she’s too young to be tied down. “The couple has had many arguments on this subject.”

Katrina, who has been staying in Salman’s Bandra apartment, shifted out to her own one (bought by Salman) on Waterfield Road. Two days ago Salman told his friends that he and Katrina were ‘just friends’.

Adds a friend of the actress, “Katrina has been in a low mood for the last couple of days and flew off to Singapore on Wednesday night to shoot for De Dhana Dhan with Akshay Kumar. More than a year ago they had gone through a similar situation, fought and almost broken up but got back together again. This time, their patch-up looks difficult.” Katrina Kaif remained unavailable for comment. Salman Khan denied that anything of the sort took place
