Actor Salman Khan is known to be the mentor and guru for several young actors whom he’s said to have taken under his wing. It’s equally well-known that the brawny actor generously doles out work-out and fitness tips to them and this includes actor Katrina Kaif.

Ever since Katrina’s signed on Dhoom 3, she’s known to be working extra hard on her hotbod, and apparently Salman’s been helping out maintain her fitness regime even on the sets of their upcoming film together Ek Tha Tiger. But according to an insider, Sallu’s so impressed with Katrina’s dedication towards fitness of late, that he’s been joking around to his friends that probably Katrina can now even give him fitness advice. “Katrina really takes her workout and fitness regime very seriously. And she’s so into her training these days and at her fittest best that Salman joked about taking fitness tips from her,” says the source.

What’s more, it is Katrina who’s been keeping an eye on Salman  and making sure that he doesn’t push himself too much, to avoid undue strain ever since his surgery. “Katrina is concerned about Salman and she keeps asking him to take care,” adds the source. According to a unit hand, this is what prompts Salman to joke further. “Salman has been ribbing Katrina about being the hottest fitness instructor of sorts,” reveals a source from the sets. The two are currently shooting for the Kabir Khan film in Thailand and in fact even had to skip filmmaker Karan Johar’s recent birthday bash, which was the talk of B-Town recently.

Meanwhile, Katrina, who is juggling her films with the two Khans Shah Rukh and Salman is now excited to start working with the third Khan Aamir soon, when they begin shooting for Dhoom 3. However, there are no comparisons between the three Khans for Katrina. “I won’t compare Salman, Shah Rukh and Aamir, but all three actors are people I’ve been keen to work with,” she’d earlier said. The actor who’s just wrapped up her Yash Chopra film with SRK adds that what she’s equally excited about are the three films belonging to different genres. “I think it’s fun when you do different things on screen rather than conform to an image and I like it like that,” she’d added.
