It looks like Kristen Stewart and Robert Pattinson are not dating but instead hooking up following their break up back in May. The "Twilight" stars have been split up for the past five months but that doesn't mean they haven't been hot and heavy with one another.

We can't ignore the fact that the hot Dior Homme model has been romantically linked to plenty of pretty faces in Hollywood including Riley Keough and Dylan Penn, but it seems his ex-girlfriend will always have a special place in his heart.

Apparently the former couple is "still hook up!" On October 9th a source told Life & Style magazine that Kristen Stewart, 23, got dropped off at Robert Pattinson's rental house where she spent the night.

According to Hollywood Life, a source said, "They've always had a passion for each other," adding, "Even though the relationship didn't work out, they still hook up with they're both in LA."

The insider revealed, "She was in a great mood" when her assistant picked her up the next morning.

"They had ordered food in and stayed up late talking. She said hanging out with Rob was just like old times."

Despite the fun the two are having together the "Cosmopolis" star has "made it clear" that they are just hooking up and not exclusive.

However, a source admitted that the actor's friends are not a fan of the new arrangement the pair have going on.

His friends are reportedly telling her that he needs to keep his distance from her, "otherwise, they might eventually end up back together."
