Robert Pattinson recently split from long-term love Kristen Stewart, while Katy Perry has been single since ending things with John Mayer in the spring.
And now it seems the pair are mending their broken hearts together after they were spotted hanging out in Santa Barbara, close to where Katy grew up.
Rob, 27, and 28-year-old Katy confused onlookers when they were seen at a wedding rehearsal of two strangers at San Ysidro Ranch.
Guest Stephanie Sands told People.com: "Katy and Rob were just sitting next to each other watching the wedding rehearsal in the main courtyard area. They were dressed very casually.
"She was wearing a hoodie and big sunglasses."
But Stephanie seemed sure there was no signs of romance between the pair.
She added: "They just sat together and watched.
"They were not affiliated with the wedding party and were not seen mingling with guests."
Katy and Rob have been friends for a while and would often spend time together along with the Twilight actor's then-girlfriend, Kristen.
But it seems instead of comforting her actress friend, Katy is choosing to spend time with Rob.
Brit heartthrob Rob dumped Kristen earlier this month after four years together when their relationship failed to recover following a cheating scandal last summer.
Kristen, 23, was caught kissing her married Snow White And The Huntsman director Rupert Sanders and though Rob took her back a few months later, it seems he struggled to trust her.
It was claimed that Katy was never supportive of the reconciliation.
A source told Life & Style magazine: "Katy never really supported Rob's decision to get back with Kristen. She always said they wouldn't last.
"Katy told Rob she didn't think their relationship could withstand the cheating scandal."
Just last Sunday, Rob was spotted moving his belongings out of Kristen's home in Los Feliz and the last of his bits were picked up by a truck the following Thursday.
But it seems he's coping OK with the break-up.
A source said: "Rob has never felt so free. He no longer has to feel weighted by a girlfriend.
"Instead of being bummed that his relationship hit a wall, Rob is simply glad to only have to be in charge of himself."
