Rob Kardashian has seemingly confirmed his romance with Rita Ora.

The reality TV star and British singer have been rumoured to be dating for some time, after they were seen out and about together many times.

Rita has always insisted she is single, but it seems the couple are now ready to go public with their relationship.

Rob has posted a series of intimate pictures of him and Rita on his Twitter page.

In one, Rita is seen with her trademark red lipstick and wearing a camouflage-print headband. She is snuggling up to Rob, who is kissing her on the cheek. The shot is captioned “Boo”, with Rita seeming relaxed and happy with her beau.

In another image, the pair are sitting on a curb with Rita placing a protective hand on Rob’s arm. As he gazes into the distance in the black-and-white shot, Rita snuggles up to him.

Rob simply called the picture “Moms”, leading to speculation the couple might have been spending time at his mother Kris Jenner’s home.

Late yesterday Rob posted another photograph of Rita, who was this time smiling for the camera. He seemed to be feeling reflective, writing: “Miss my ORA boos (sic).”

Earlier this year, Rob and Rita got temporary tattoos of each other’s names on their knuckles. He was asked about it in August, but remained coy about their relationship.

“Rita is in the U.K. I'm just a fan. That's all. I'm a big fan. She does have tattoos,” he laughed.
