Another Robert Pattinson & Kristen Stewart engagement rumour

It has been reported, yet again, that Robert Pattinson and Kristen Stewart are engaged.

According to a report by Aussie magazine Fabulous, the Twilight co-stars and rumoured real-life couple got engaged after their argument about Kristen spending too much time with actor Garrett Hedlund.

Rob apparently gave Kristen an “ultimatum” to prove herself to him.

“But don’t expect a big announcement any time soon!” a source said.

“They’re planning to keep things under wraps for a while.”

“The whole engagement was a very spur-of-the moment thing. Rob didn’t even have time to buy Kristen a ring.”

This report comes not long after Look magazine claimed Kristen had dumped Rob, because she wanted “time-out” from their relationship.
