Hot Couple: Robert Pattinson & Nikki Reed!

Laineygossip.com is reporting that Robert Pattinson is hooking up in Canada with onscreen "sister," Nikki Reed (Rosalie). LOVE IT!

Later that night (Sunday) they met up with friends, then ended up at one of the label parties after the Junos with Kristen Stewart and her boyfriend Michael Angarano. Am told Rob and Nikki spent much of the time talking to each other, heads bent close together.

My sources tell me exclusively that at the end of the evening, or early morning depending how you see it, the four of them left the event, hugged before parting ways (a weird 4-way group hug), Kristen and Michael hopped in a cab, and Nikki and Rob walked further up the block… arms wrapped around each other on their way home.

She stayed with him overnight, was supposed to be back in LA on Monday….

But never showed.
