Russell Brand and Jemima Khan spark engagement rumours

Russell Brand and Jemima Khan, who have been dating since last summer, have sparked engagement rumours after the beauty was spotted wearing a diamond ring in London and another day in a restaurant.

A source told the Mirror that the sparkler looked like an engagement ring and was very pretty and classy.

The insider asserted that 40-year-old Khan looked very happy.

Although, the 38-year-old comedian, who was earlier married to signer Katy Perry, has openly confessed to being in love with the mum-of-two, the pair hasn't officially announced anything yet.
