Katy Perry, Orlando Bloom enjoy low-key date

London: Katy Perry and Orlando Bloom enjoyed an evening together at Sunset Hotel's Tower Bar in West Hollywood, California over the weekend.

Perry, 31, and Bloom, 39, looked like the most romantic duo, reported Female First.

"They were super low-key and having a good time. They were really sweet with each other," a source said.

"They looked very loved up and really into each other. They were comfortable letting everyone see them as a couple - lots of PDA and hand-holding. It seemed very romantic and they both smiled a lot, and looked to really enjoy each other's company," the insider said.

Bloom has apparently introduced the "Roar" hitmaker to his son Flynn, who he was with ex-wife Miranda Kerr.
