AnnaLynne McCord and Kellan Lutz apparently aren’t doing a very good job of keeping their romance under wraps. Though they refused to pose for pictures together at a Fourth of July party — and the “Twilight” hottie insisted to the New York Daily News that he’s “quite single” — he and the “90210” beauty were reportedly sighted making out in the bushes.

But it seems the great outdoors wasn’t adequate for their purposes. A Page Six spy revealed, “At one point, they went into a room upstairs arm in arm and Lutz jokingly announced to the people hanging out inside, ‘We’re looking for a place to’” — er, get to know each other better.

“Someone directed them to a bathroom, and they went in,” adds the source. Way to keep it classy, kids!
