Kristen Stewart: Robert Pattinson Is "My Husband"

Our friends at Limelife have revealed that while Robert Pattinson and Kristen Stewart are filming on the Eclipse set, they've begun referring to each other as, well, spouses.

Eclipse insiders have told OK! magazine that Kristen giggles to co-stars calling Robert "my husband," as in, when she's looking around for him on set, she'll ask, "Has anyone seen my husband?" Robert reciprocates by saying, "Have you met my lovely wife, Kristen?" The insider says that on set, they behave like lovestruck teenagers.

The revelation doesn't exactly shock us. Reports in the last couple weeks have suggested that Kristen and Rob have bought a three million-dollar mansion together in Los Angeles. We're also told that on their days off from filming, they snuggle up inside Robert's cozy hotel suite in Vancouver and rarely come up for air.

And now marital make-believe? While, like the Limelife gang, we might not bet a Webby on it (the engagement rumors? We won't pass those along until there's a spine-bending rock on her finger), it's all the more evidence that Robert Pattinson and Kristen Stewart are a thing. Limelife is speculating that their romance resembles "college dorm hook-ups," but put a sexy English vampire and a cheeky American girl on the same room service bill and what you'll get is something unconditionally intriguing.

OK! reports that execs for New Moon have told Rob and Kristen to keep their affair under cover until after the second film in the Twilight series comes out in late November. This way, we're more likely to believe the onscreen romance between Kristen and Taylor Lautner. Celebrity Love: RPattz Worried Kristen Wants Taylor Lautner
