The two dated for 10 months before calling it quits in February, but several concertgoers tweeted they saw the pair holding hands and kissing while at Sheeran’s concert.
They both wore similar black baseball-style hats with Perry’s covering her blonde pixie hair as she stayed close to Bloom. She also wore a red bomber jacket, and leather black skirt.
One fan posted photos of the two sitting close to each other, tweeting Perry, 32, walked out of the concert with Bloom, 40, following close behind with a group of friends.
Another fan on Twitter wrote that she saw the two backstage walking together and holding hands.
An onlooker told PEOPLE at the time that the duo didn’t interact at the party much except for posing for a photo together and mingling with their own friends.

At the time, a Perry source said that over the last few weeks, the relationship “just became more and more work to make it work,” said the source. “Because this wasn’t something permanent, it just became time to take a break.”
“Katy didn’t spend much time with Orlando,” the source said. “They got together for a photo, but that was about it.”
In April, they reunited briefly at a party in West Hollywood. A source told PEOPLE that “Orlando and Katy had a quick hello and a brief chat.”
“They weren’t too friendly and hung out with separate friends at the party,” the source continued.
