Katy Perry has opened up about rumours swirling around that she is dating Orlando Bloom again. The Roar singer has said that when "people get older, lines get blurred".

Speaking on SiriusXM Hits 1 on Monday (21 August), the songstress said that she keeps the people she loves close to her even though they could be "in and out of your life".

"For me, it's never so extreme. So, when you get older, lines get blurred," she said. "And you know what, I'm really busy. I'm about to go on tour for another year."

The former couple reignited romance rumours after they were spotted "kissing and cuddling" at Ed Sheeran's concert on 12 August. They announced their split in February after dating for a year.

"They definitely seemed like they're back together," an eyewitness told E! News. "They cuddled most of the night. She sat on his lap most of the night and shared kisses."

"They looked like they were having the time of their lives," the person continued. "People didn't really bug her. I don't really think people knew it was them because they had hats on and stuff."

Perry also talked about her feud with Taylor Swift after she was asked if she would perform alongside the latter in the future.

"Listen, I'd love for the beef to end. I'd love to take if off the BBQ. I'm down, but I haven't heard anything of it," she said.

This is not the first time Perry has talked about putting an end to their feud.

"I am ready to let it go," Perry said in June. "I forgive her (Swift) and I'm sorry for anything I ever did, and I hope the same from her."

"I love her, and I want the best for her. And I think she's a fantastic songwriter," she said. "I just really truly want to come together in a place of love and forgiveness and understanding and compassion."
