The trio came together for the 30th annual Stellar Awards in Las Vegas in March (15) and they also teamed up for a brief performance as part of Beyonce's 2013 Super Bowl halftime show spectacular, but there are no plans to repeat those special moments, according to Kelly.
"It hasn’t been something that we've talked about at all," she tells Us Weekly magazine.
But she admits she, Beyonce and Michelle Williams still like to get together from time to time, and just "enjoy each other".
"Whether it’s been about our music, whether it’s been about motherhood or our personal lives, that’s what it’s really been about," she explains. "That’s been the most beautiful part.
"We absolutely are (family). We love each other."
