Katy Perry and Orlando Bloom’s ‘sweet’ date

Katy Perry and Orlando Bloom were "really sweet with each other" as they dined together in West Hollywood.

The happy couple were spotted enjoying a "super low-key" evening and a bite to eat at Sunset Hotel’s Tower Bar in California.

A source told PEOPLE magazine: "They were super low-key and having a good time. They were really sweet with each other.

Meanwhile, the ‘Dark Horse’ hitmaker and the ‘Pirates of the Caribbean’ actor enjoyed a romantic trip to Kauai, Hawaii earlier this year.

An insider said at the time: "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."

And it was previously claimed that things have gotten so serious between the pair that he has introduced her to his son Flynn, five, who he was with ex-wife Miranda Kerr.

An insider said: "Katy and Orlando are doing really well. They have been hanging out a lot over the past two months. They are a very chill pair … They both communicate great and laugh when they are around each other.

"Katy has met Flynn, and they get along wonderful. She thinks he is so cute and such a well behaved kid! Katy would [also] like kids one day, and she is vocal about that."
