Ranbir Kapoor to do a cameo in SRK's film?

Ranbir Kapoor will be making a cameo appearance in Shah Rukh Khan's upcoming film, The Ring, reports a tabloid. In Ranbir's last release Ae Dil Hai Mushkil SRK had done a cameo, looks like the former is returning the favour.
Apparently, Imtiaz Ali who is directing the SRK-Anushka Sharma starrer wanted a strong actor to play a small role in the film. Imtiaz mentioned it to Ranbir who immediately agreed. Ranbir and Imtiaz share a close bond since they did Rockstar together.
He will be playing Anushka's finace in the film. Anushka plays a tourist who falls in the love with her guide (SRK) while travelling across Europe and looking for her lost engagement ring.
