Pawan Kalyan and Mahesh Babu have been pally stars for long now. Though they do not wear their professional admiration for each other on their sleeves, their proximity has never been in doubt.

True to this style, the Prince greeted his superstar colleague on Twitter wishing him a happy birthday, though Pawan doesn't have a twitter id because he doesn't socialise either online or offline.

Prior to the release of Komaram Puli last year, Mahesh was the first star to congratulate his friend on the roaring success of the film's audio saying he thoroughly enjoyed listening to the AR Rahman musical.

Going by this, it may well turn out that Pawan and Mahesh will do a multi-starrer in some years. Bollywood audience may never get to see Aamir Khan and Shah Rukh Khan teaming up given their blow hot blow cold relationship in real life, but the biggest Tollywood heroes shall come together for a film sooner or later.
