Rihanna and Rob Kardashian were spotted a day and a night Saturday, racing and clubbing. Is love in the air?

The 24-year-old singer and the 25-year-old reality star went go-karting at Racer’s Edge Indoor Karting in Burbank, California Saturday afternoon.

Rihanna donned an oversized black-and-white varsity jacket and black knee-high boots, finishing her look with gold accessories and red lipsticks.

Kardashian was seen in a green button-up and mustard yellow pants, paired up with Nike trainers and a New York Yankees baseball cap.

The same night, the duo were seen heading to the Playhouse nightclub in Hollywood , E! News reported.

Especially Rihanna looked annoyed at paparazzi.

“Rob and Rihanna clearly did not want to be pictured in each other's company, as they entered and left the club separately, Rihanna offering a one fingered salute to the waiting paparazzi," said RadarOnline.

Rihanna just recently opened up about her love for Chris Brown to Oprah, while assuring fans that they are not getting back together.

In an intimate interview with Oprah Winfrey on "Oprah's Next Chapter" Sunday night, Rihanna confessed that she and Chris Brown still "love each other.”

Rihanna described the infamous incident of Brown assaulting her in 2009 as "humiliating" and "hurtful," but emphasized her love for Brown that has not died.

"He was the love of my life. The first love," Rihanna said. "No one could feel that more than me. Nobody felt what I felt. It happened to me in front of the world," she said of Brown's violence.

"I lost my best friend. Everything I knew switched. Switched in a night. I couldn't control that," she said. "As angry as I was, as angry, hurt and betrayed I just felt like he made that mistake because he needed help. Everybody's gonna say he's a monster without looking at the source. Who's gonna help him?"

"We love each other and we probably always will and that is not anything that we are going to try to change. That is not something you can shut off if you are ever in love."

Rihanna said that she could forgive Brown by finding the way to forgive her own father for abusing her mother.
"I have to forgive him, because I cared about him still," she said. "The minute I let go of that, I started living again."

Rob Kardashian, on the other hand, has allegedly been dating singer Rita Ora since late 2011. The duo showed off fake tattoos of each other’s names on their hands, fueling the dating buzz.

"Rob's family make their lives public,” Ora told Glamour last month.

“Me? I'm very private. He's a great friend. But the only relationship I'm having now is with the tour bus."

Is there some drama awaiting these stars?

Kardashian on Friday sent a suggestive tweet to Rihanna, "A man's biggest mistake is giving another man an opportunity to make his woman smile."
"This!" he continued. "Don't f*** it up!"
