Kelly Rowland's Bikini Beach Day Is Anything But Boring

Of all the celebrity beach days we've seen this week, Kelly Rowland's was arguably the most fun-filled. The singer sported a purple bikini and printed caftan for her day in the Miami sun on Thursday, but rather than spend the whole afternoon basking in the sun — which she did do — Kelly made the most of her time on the sand by playing soccer with a couple of cute kids, even stopping to help them build sand castles. It wasn't clear whether the little ones were in Kelly's beach brigade or not, but it still resulted in some pretty adorable snaps.

Kelly, who recently became engaged to her manager, Tim Witherspoon, rang in 2014 by hosting a New Year's Eve party at the Room Service Lounge in Miami. Her former Destiny's Child bandmate and BFF Beyoncé was also in Florida, where she and husband Jay Z partied at Diddy's bash along with Drake, Jamie Foxx, and Pharrell Williams.
