While shooting a stunt in Goa, Ranbir was floored by Kat’s bravado.
The scene required the duo to jump off a jet ski and cling on to a ladder that was suspended from a bridge overhead. While Katrina was able to pull off this stunt with impressive swiftness and finesse, Ranbir kept struggling.
Seeing Katrina’s derring-do, Ranbir gave her a new nickname: “Rambo ki sister Sambo”. The moniker wasn’t given in jest; Ranbir says he’s truly impressed by Katrina’s ability to do such a risky action scene.
Katrina though is flattered by Ranbir’s nickname, but laughs it off as just one of his funny one-liners.
