It's no surprise why Karan Johar's still gaga over Madhuri Dixit.​

Dixit, who turns 46 today, will be seen shaking a leg with Ranbir Kapoor in a song titled 'Ghagra' in Johar’s forthcoming production Yeh Jawaani Hai Deewani in which Kapoor is paired opposite Deepika Padukone.

But Johar is more keen on seeing Kapoor's chemistry with his childhood crush Dixit, as opposed to his (Kapoor’s) chemistry with real life ex Padukone.​

And judging by this video we can see why. Dixit still looks as fresh faced as ever, and it seems a trip to the movies will be worth it for this song alone.

​Yeh Jawaani Hai Deewani also stars Kalki Koechlin and Aditya Roy Kapur and releases worldwide on 31 May 2013.
