A source tells E! News the duo partied at hotspot nightclub Bootsy Bellows Friday night, hanging out from around midnight until closing, after grabbing dinner together.
Although the pair partied together, Bieber didn't drink and they kept it platonic, with "nothing flirty happening between the two of them."
"Rita and Justin are good friends," the source said. "They had a great night together with a small group of friends partying and dancing."
When asked about falling in love with the DJ, Ora told the mag, "He got something out of me that I never thought I had. Yes, like falling in love. I just didn't think I had it. I'd never experienced it before. And I was just like in the wilderness, thinking, "Will it ever happen?'"
Ora and the Biebs weren't the only ones hanging out in Tinseltown Friday.
Drake was also spotted out and about, grabbing dinner at Mastros and then having a guys night out at Hooray Henrys.
