What Bollywood fan doesn't love a good dose of early 2000s nostalgia? To the delight of blockbuster buffs, B-town queens and old friends Kareena Kapoor Khan and Rani Mukerji – or Pooja and Tina from the hit film Kabhi Khushi Kabhie Gham – embraced on camera in a candid clip recorded by none other than filmmaker Karan Johar.

"Jab Poo met Tina, that's all!" captioned Karan as he shared the clip on his Instagram handle. Their excitement bubbling over, both Kareena and Rani can be seen enveloping each other in a tight hug, with Kareena planting a firm kiss on Rani's cheek.

As Karan recorded the moment, we can hear him slip into K3G mode as he quips the iconic line in Hindi, "Hi! Hi! Will you be friends with me?" (For those who need a reminder, in the film, it is Hrithik Roshan's Rohan who asks for Poo's friendship.) Caught fully in the moment, Karan then tries on one of Kareena's K3G lines: "I like it, I like it - I'll only go to the prom with you!"

Burying her face in her hands, Kareena says, "Oh God! Why are you doing this?" Ignoring her, Karan once again tries on the "Will you be friends with me?" line on Rani. With a mock-serious look - magnified ever more by her black-rimmed square glasses - Rani declares, "Never!" before bursting into giggles.
