Another rumor surrounding controversial couple, Robert Pattinson and Kristen Stewart, claimed that the actor asked Kristen's hand for marriage.

The British actor is said to be "desperate" to get back with his ex-girlfriend. However, this time, he wants her to "truly commit" to him.

A source of The Times said, "Rob told Kristen the only way he can forgive her affair is if she truly commits to him. Rob has been keen to marry Kristen for quite a while and he doesn't want to get back with her unless he knows she means it for life too."

"Although Kristen broke Rob's heart he has realised he can't live without her. He never stopped loving her and he believes she still loves him. He is desperate to make it work and wants to give her another chance but not unless she proves she really wants it too," the source quickly added.

Before the news about Kristen's infidelity broke out last summer, it was rumored that the 26-year-old actor had plans to pop the question to the actress.

With the news that the two is now back together and are working things out between them, rumors claimed that the two are in it for a month's trial for their relationship. They are testing the waters if their relationship will work.

Reports claimed that though the pair is no longer living together, they meet up regularly but Robert has laid down some ground rules. The actor banned the actress from contacting Rupert Sanders who she had an affair with.

According to Now magazine, Rob agreed to take Kristen back but forbid the stress from seeing Sanders.

"On the Road" actress Kristen Stewart was caught in a steamy love affair with her "Snow White and the Huntsman" director. Photos immediately went viral on the internet and the two issued separate public apologies for their "momentary indiscretion."
