(WENN) - Kim Kardashian’s little brother Rob appears to have confirmed long-standing rumors he is dating R&B star Rita Ora by posting a picture of the pair kissing on his Twitter account.

Rob Kardashian and the British singer originally played down summer reports they were in the midst of a blossoming romance, with Ora telling Complex magazine, “It’s not really a relationship. It’s not that intense.”

She added, “He’s a cool guy. We’re close. We’re good friends. I got his back and he’s got mine.”

But on Tuesday the 25 year old sparked fresh new speculation they were more than just friends after uploading a shot of the couple posing for a picture as he plants a big smooch on the side of her mouth.

This week he also shared an image of the pair cuddling on the sidewalk and another snap of Ora in a photo with her sister Elena, alongside a caption, which reads, “Miss my ORA”.

Rob isn’t the only Kardashian dating a musician – big sister Kim has been romancing rapper Kanye West since the beginning of the year.
