PIX: Ranveer, Ranbir, Kareena party with Arjun Kapoor’s birthday bash

Several Bollywood friends turned up at Tevar actor Arjun Kapoor's Mumbai residence to wish him a happy 30th over the weekend.

And it looked as if all of his A-list contemporaries were in attendance, including Deepika Padukone's former beau Ranbir and current boyfriend Ranveer -- two actors you've probably haven't seen together before!

Here's birthday boy Arjun Kapoor, who turned 30 on June 26, ushering in his birthday with an array of delectable-looking cakes and other baked goods.

And here we have Ranbir Kapoor (still working the Johnny Balraj look from Bombay Velvet?), arriving with girlfriend Katrina Kaif.

This also happens one of the rare times you've spotted the famous lovebirds together.

In walks Arjun's best bud in Bollywood and Gunday costar Ranveer Singh, relatively tamely dressed in a red jacket and a fedora.

Karan Johar, being all, 'Is this party going to be any fun at all,' as he walks in.

And BAM!

There you have it.

Ranbir, KJo, Ranveer sharing the frame with the beaming birthday boy!

And Karan Johar channeling his inner social butterfly along side Arjun's actress cousin Sonam Kapoor and Jacqueline Fernandez.

And oh, Kareena Kapoor was there too.

Aditya Roy Kapur, who arrived to the party with Ranbir, joins the selfie brigade.

 Arjun's doting sister Anshula Kapoor, seen here with Jacqueline and a friend, was quite the party reveller too.
