Rita Ora has two things to celebrate about. First, her anthemic single 'R.I.P.' (Featuring Tinie Tempah) is the No. 1 song on the U.K. music charts, according to Official Charts Company. Second, she has a new man in her life, Rob Kardashian.

The U.K.'s Daily Mail Online spotted Ora and Rob together at London's posh nightclub Whisky Mist as they celebrated her chart-topping achievement. The couple try to thwart the paparazzi by not arriving together, but Rob made it official on this Twitter account that Ora was indeed his main chick.

After posting a picture of the 21-year-old songbird, he then congratulated her with his tweet, "You did it. I love you and you're my wife."

Whoa! Wedding bells, already? Slow down, R.Dash, she's hasn't even released an album, yet.

He then posted a photo (above) of Ora holding a chocolate-covered replica of a champagne bottle with "R.I.P. #1" engraved on it. "I LOVE MY WOMAN! I'm so proud of You!," he later tweeted.

Aww, isn't he sweet?

The song 'R.I.P.,' which was penned by Drake and produced by Chase And Status, is Ora's second No. 1 single in the U.K. She scored her first chart-topper back in February with DJ Fresh's 'Hot Right Now.'

Ora is ecstatic to have two hit songs under her belt and thanked the fans for helping her reach this new plateau. "You don't understand what this means to me," she said. "Thank you so, so, so much for this! I love you!"
