Kelly Rowland secretly married her manager Tim Witherspoon in Costa Rica last week, it has been claimed.

The former Destiny's Child singer and her manager Tim Witherspoon tied the knot in a secret ceremony in Costa Rica last Friday (09.05.14), it has been claimed.

A source told Us Weekly: ''It was a quick, simple ceremony - only around 30 people.'' Among the guests were Kelly's former bandmate Beyonce and her sister Solange.

Although the nuptials haven't been confirmed, Beyonce had posted a photograph to her Instagram account on the big day wearing what appeared to be a bridesmaids dressed but was captioned only: ''Good morning.'' Speaking last December, 33-year-old Kelly admitted she and Tim had been engaged for some time.

She said: ''He put a ring on it. It's been a while. We've kept it very, very low - for years, to be completely honest.'' Kelly also revealed her boyfriend of four years proposed on Skype while she was in Bulgaria.

She said: ''He put a ring on it! He asked me first on Skype and I was like, 'We're so far away from each other.' But it was so late, I remember we were both just kinda like, honestly, just staring at each other ... and he asked me, and it was just that simple to say yes.''

The 'Kisses Down Low' singer was previously engaged to footballer Roy Williams, but they split in January 2005 without making it down the aisle.
