KP is on cloud nine these days!

Katy Perry appeared on Jimmy Kimmel Live! last night and dished all the details on her recent engagement to Orlando Bloom, and she seems happier than we've ever seen her!

"It was very sweet. It was Valentine’s Day … we went to dinner and I thought we were going to go see some art after dinner but we pulled up to a helicopter," she revealed.

"Very Bachelor!" the late night host joked.

"Yeah. I’m glad I don’t have to go on that show now. It was really sweet. He asked me to marry him in a helicopter. The funny part is we had champagne in the helicopter and the [ring] box was in his pocket and he had written down everything he wanted to say on a note. So I’m reading [the note] but I’m hearing the champagne is broken and the bottle’s everywhere … he’s pulling out this box that’s too big for his coat pocket, rips his coat pocket and his elbow goes into the champagne," she continued.

Eventually the British hunk executed things, but he still had one more surprise.

"We landed on a rooftop [in Los Angeles] — my whole family was there, and all my friends. He did so well," she gushed.

So how did the lovebirds first meet?

"In-N-Out plays a big role in my life. We bonded over an In-N-Out burger about three years [ago] at the Golden Globes. He stole one off of my table … he took it and I was like, ‘Wait! Who — oh, you’re so hot. Fine, take it.’ And then I saw him at a party and I was like, ‘How are those onions resting on your molars?’ He’s like, ‘I like you.’ And then, you know, cut to," she joked while showing off her new rock.

She's living a teenage dream!
