Romance rumors have swirled around singer Rita Ora and "Keeping Up With the Kardashians" star Rob Kardashian for months, and over the weekend, the pair added more fuel to the fire, trading a series of cutesy tweets.

Kardashian evidently started things off by professing his fondness for the rising U.K. songstress, and while he's since deleted the post and an accompanying photo, Ora's re-tweet tells the tale.

"'@RobKardashian: Love her though. Flaws and all. @RitaOra,'" she re-tweeted, adding an affectionate "LOVE! X" to the end of her post.

In an earlier post, the "R.I.P." performer went the emoticon route, leaving little doubt she and the onetime "Dancing With the Stars" competitor are an item.

":):):) @RobKardashian," she replied to him via Twitter.
