Katy Perry and Orlando Bloom just can't get enough of each other ... hanging out twice in less than a week.
Perry was seen in Bloom's backseat Saturday after a party at Robert Downey Jr's Malibu pad, and she looks pretty cozy. From what we can see, there wasn't anyone else in the car so it's a little odd she took the back, but we've seen stranger.
Rumors the two were officially a couple started swirling earlier this week after they were spotted at the same birthday party in L.A.
It's unclear where Katy and John Mayer stand ... she partied with the singer til 4:30 AM after one of his shows just over a month ago.
Let the couple nickname suggestions begin.
