Actress Katrina Kaif turned 28 yesterday. Since, it was her birthday, the rumours were doing the rounds that Katrina's ex-boyfriend Salman Khan would be throwing a surprise party for her. But, we still wonder, what did Kats actually do on this special day of her life?

Well, as per the reports, it was a working day for Katrina. The actress has been very busy with her filmy activities. A source had earlier told a leading daily that Katrina "will dub for her upcoming film ‘Ek Tha Tiger' with Salman Khan as well as train for her action film ‘Dhoom 3' with Aamir Khan. As her house is under renovation, she also plans to shop for some stuff. Though none of her family members are in Mumbai, some of her pals have planned a quiet celebration."

The sources further reveal that the actress has been shooting for 18 hours a day since the past few months. It is also believed that Katrina is someone, who prefers having quiet birthday, but it turns out to be something else at the end of the day. Well, it looks like all work and no play for Kats, even on her birthday.
