But what binds the two together is their earnest struggle to get better at the national language ... while Kat grew up in Hawaii, Marzi is the quintessential Bawa.
The two had barely spoken any Hindi before their entertainment careers took off. Moreover, the two are great friends as Marzi has choreographed Kat in many films.
So when Katrina landed up with Salman Khan to promote their upcoming film Ek Tha Tiger on the sets of DID L'il Masters, the two had plenty to bond over.
While Salman joined grandmaster Mithun Chakraborty in pulling Marzi's leg over his terrible Hindi, Kat couldn't help but feel sorry for him.
When Salman joked that Zee TV would need to use subtitles to decode what Marzi says when he attempts Hindi, Katrina defended him saying his efforts to speak better Hindi in each episode were worth lauding.
Apparently, the actress has often been at the receiving end of similar jokes about her Hindi and so could easily empathize with him.
But Salman being the prankster caught onto a Hindi phrase that Katrina said when he and Mithun Da were ragging Marzi beyond a limit over his poor knowledge of Hindi. Katrina quoted a phrase she had heard that defined their ragging and said, `Aap Marzi ko itna chidhate hai jaise koi ek chipkali ko khichke magarmach banate hai (You tease Marzi so much as if you're stretching a lizard to become a crocodile).`
Both Salman and Mithun Da jumped in and hounded Marzi saying Katrina had called him a chipkali leading to a laughter riot on the sets.
In the course of the episode when she started commenting on the contestants' acts in English, Katrina found Salman egging the children on to ask her to repeat her comments in Hindi.
A flustered Kat did her best to translate her comments in the simplest hindi possible, much to the amusement of the audience.
The episode will be aired this Sunday.
