So Robert Pattinson is talking about marriage to Kristen Stewart...

Robert Pattinson is still crazy about Kristen Stewart, but he's less crazy about the idea of marriage. In a new interview with BlackBook magazine, the actor responds to recent rumours that he popped the question to his Twilight costar.

"There was a magazine, with these pictures, saying I was getting married. No one ever knows what is true or what isn't," Pattinson, 26, explains. "Even my own mum called to ask me if it was true."

Unfortunately for Twihards (and the original Mrs. Pattinson), reports of Pattinson and Stewart's impending nuptials were false.

"It's not [true]. At least, not yet," Rob concedes. "But it is true that Kristen has always done something to me that others haven't."

Of course, Rob and Kristen have already had one wedding, when their characters Edward and Bella got hitched in Breaking Dawn - Part 1. At the time, Rob joked that they were now "technically" married, since the wedding scene featured a real priest performing an actual ceremony. In a separate conversation with iVillage, Pattinson said that the Breaking Dawn scene made him ponder his own future wedding -- although not necessarily in a good way.

"You're kind of just standing there like a penguin at the end of the aisle," the British actor mused. "You definitely realise it's definitely the bride's day. The groom is just a prop."

One thing's for sure: Pattinson, who stars in the upcoming Cosmopolis, has always been wild about Stewart. In the BlackBook interview, he reveals that after they first met (but weren't yet a couple), he wrote sad love songs about her and sang them at open mic nights around Los Angeles. "I was just trying to rip off Van Morrison," he jokes. Hey, if he does marry Kristen, maybe he can work one of those songs into the ceremony. Better yet-- maybe Van Morrison could actually sing it.
