The singer reunited with the fashion designer and model 25 years after she appeared in his 'Nice & Slow' music video.
In a video shared to social media, a bare-chested Usher got up close and personal with Simmons -- marking something of a reunion between the singer and the model 25 years after she appeared in the music video for his song "Nice & Slow."
Kardashian made sure to share the hot exchange to her Instagram story, showing Usher standing in front of Simmons, singing "Nice & Slow" before feeding her a chocolate strawberry.
After Usher returned to stage, Simmons couldn't help but laugh while fanning herself following the steamy moment.
The Simmons serenade comes just a week after Usher sang to Kim, who came out to watch his show last weekend as well.
The reality star had a special moment as Usher danced over to her section and began to sing "Superstar." Before going into the first verse, the singer gave the SKIMS founder a special shout-out, sharing, "What up Kim? You made it!"
Kim's previous trip to the Usher show came six months after she missed his concert -- due to inclement weather. In October, Kim tried to pull off the ultimate birthday surprise with a trip to the Usher concert. Unfortunately for the birthday girl and her crew, they didn't make it to the show due to windy conditions.
