Three people have been shot at a restaurant owned by Real Housewives of Atlanta star Kandi Burruss.

Witnesses claim that the gunman shot three people inside before fleeing the Old Lady Gang restaurant in Atlanta, Georgia, just after 9pm on Valentine's Day.

East Point police said the gunman shot another man and also hit two other bystanders in front of horrified diners.

All victims were taken to a local hospital with non life-threatening injuries, Fox 5 Atlanta reports.

The names of the victims have not been released yet.

Witness Brynae Kinsey told CBS46: "We were waiting for our spot at the Juicy Crab, and we were waiting outside actually at that bench right there. We heard two gunshots and I seen somebody run out that door, and I ran.

"I just heard her scream 'ahhh,' and then I heard two pops. Pop, pop. I just wondered what was going through his head for him to pop off like that."

Ricka Franklin, who told Channel 2 Action News her brother works at the restaurant, described a chaotic scene inside the building when it unfolded.

"While they were back there cooking and stuff, they just heard gunshots,” she said. “All of a sudden, the customers ran to the back where they were."

Just minutes before the shooting, Kandi had posted a tweet message to her husband.

She wrote: "Happy Valentine’s to the love of my life! I love you babe!"

The Old Lady Gang restaurants are owned by Kandi, who shot to fame for co-writing Grammy Award-winning hit No Scrubs and her husband, Todd Tucker.
