Well that was possibly the worst kept secret in showbiz.
The 'RIP' singer has spent the best part of this year denying that she was romantically involved with the reality TV star.
Now, however, it seems that Rita Ora has given up trying to hide her relationship.
Taking to Twitter, Rob Kardashian posted two candid shots of the couple.
The first sees Rob kissing Rita with the affectionate caption beneath the photo simply reading "Boo."
The second shot shows the two cosying up to each other on the side of the road.
Naw, young love eh?
Earlier this week, Rob posted a slightly less flattering tweet about the 'How We Do' singer.
Alongside a picture of Rita sitting in his car, the reality star wrote: "This crazy b***h just stole my car."
Rita Ora has previously said that Rob is nothing more than a friend saying: 'He's a great friend. But the only relationship I'm having now is with the tour bus.'
Hmm, well from the looks of these pictures the tour bus has some serious competition on its hands.
Rob Kardashian rose to fame after appearing on hit reality show 'Keeping Up with the Kardashians' alongside his sister Kim.
Kim's rapper boyfriend Kanye West has since appeared on the show which makes us wonder if Rita will follow suit and make a cameo during the next series, now that her relationship with Rob is out in the open.
We can only hope!
