Family and friends are saying rapper Jay-Z and girlfriend Beyonce Knowles were married on Friday, but Jay-Z wasn't giving away any secrets Saturday night during his concert in North Carolina. The singer appeared on stage without a wedding ring and didn't mention his new bride or the wedding.

Co-headliner Mary J. Blige couldn't stay mum on the subject, however, and when she took the stage as part of the "Heart of the City" tour she shouted-out to the audience, "Congratulations to my man, Jay-Z, and my girl B."

Music superstars Beyonce and Jay-Z have tied the knot, according to reports. According to a source, the "Crazy In Love" singers have gotten married in a very private ceremony Friday.

A source tells People magazine, "It happened earlier this evening. Jay wanted it to be a really private affair - close friends and family."

Kelly Rowland had a secret boob job last year.

The former Destiny's Child singer underwent the cosmetic procedure last October because she wanted to boost her modest bust.

Kelly Rowland had a breast implant and is proud of it. The former Destiny's Child singer says her new look makes her "feel complete."

The "Dilemma" singer speaks up about her new enhanced look saying she went from size A cup to a B cup late last year. Although she has admitted to the breast augmentation surgery, she has denied she did it to compete with former co-member Beyonce Knowles.
