Sisters Rhea Kapoor and Sonam Kapoor share thin space between each other and hold more than a friendly relationship as siblings.

Rhea wanted to make her sister, Sonam's birthday special and therefore, she planned an all girls birthday for Sonam in London, where they will be spending a few days chilling out.

Reportedly, it is going to be all girls gang party except for one of their dear friends Kunal Rawal, whom Rhea lovingly considers a part of her gang.
