KARACHI: Twilight couple Robert Pattinson and Kristen Stewart, are notoriously private when it comes to their relationship, but it appears things are becoming very serious for the couple. They have been spotted shopping for engagement rings at Neil Lane Jewelers in West Hollywood, escalating rumors the power couple are about to become engaged.

Shoppers at the store said Kristen Stewart was looking at different colored diamonds for her quirky ring.
News that they were looking at engagement rings comes after a friend of the pair recently revealed that they were ready for marriage.
The relationship between Pattinson and Stewart is said to have sped up in the last year with a friend saying: ‘In the past year, they’ve really heated up – moving in together, travelling together, introducing each other to friends. She loves Rob, and she's finally ready — an engagement is a logical next step."
In other related news, Pattinson has revealed that Kristen is the 'only person' whom he can relate to. The actor said, "She understands exactly how I feel. She is an ambitious woman who wants to grow as an actress. She has an excellent radar for what is good and challenges me constantly."
Speaking of their recent appearance at the Cannes Film Festival, Pattinson admitted: "In the end, it was amazing to have each other's support. Her presence at the gala screening of Cosmopolis made me really nervous."
He added: "She was sitting in front of me. I kept looking at the back of her neck, trying to find out if she was liking the movie or not. I only calmed down when, at the end, Kristen told me she loved it."
Recent reports claimed the ‘vampire duo’ have also been looking at houses online so where they could raise their future family. But with Stewart and Pattinson both keeping ‘mum’ on engagement rumours, nothing is written in stone.
