The 24-year-old "We Found Love" singer raced the 25-year-old reality star with some pals in Burbank, Calif. at Racer's Edge Indoor Karting, Daily Mail reports.
After the group had their fill of go-karting, Rihanna and Kardashian were spotted heading to Playhouse nightclub in Hollywood. Kardashian dressed casually for evening in orange pants, a green button-up shirt and baseball cap. Rihanna wore a varsity jacket button-up coat and black knee-high boots with bright red lipstick.
Back in December, Us Weekly confirmed that Kardashian was dating R&B singer Rita Ora, 21. The couple went on a double date with Kim Kardashian and Kanye West in May. According to the Daily Mail, Ora was photographed last week leaving a London nightclub with Rizzle Kicks' Harley Alexander-Sule.
In a candid interview with Oprah Winfrey last week, Rihanna said she still has feelings for her ex Chris Brown -- even after the 23-year-old was arrested for physically assaulting her in February 2009. "We love each other and we probably always will, and that's not anything that we're going to try to change," Rihanna told Winfrey, 58. "I think he was the love of my life. He was my first love and I see that he loved me the same way. I truly love him. The main thing for me is he's at peace. I'm not at peace if he's not happy or he's still lonely. I care. It actually matters that he finds that peace."
