Kelly Rowland's beau put a ring on it! The "Kisses Down Low" singer, 32, is engaged to marry her manager and boyfriend Tim Weatherspoon, sources confirm to Us Weekly. (Bossip was first to break the news of their engagement.)

"She has been showing [the ring] off to friends and family and is very happy," one insider tells Us. "She wants to...enjoy [it] and celebrate for a bit longer."

Rumors that Weatherspoon had popped the question circulated when Rowland was seen wearing a large diamond ring in a video on a pal's Instagram account.

This will be the Destiny's Child singer's first marriage. She was previously engaged to football player Roy Williams; they split in January 2005, two months before their planned wedding.

"I was too young for marriage," the British X Factor judge later told Cosmopolitan UK of their breakup. "But sometimes you fall down and you learn from it."
