British pop star Amelle Berrabah has exchanged vows with her fiance less than a week after announcing her engagement.

The former Sugababes singer went online last week (12Oct14) to show off her new diamond ring which was presented to her by HitMan Records boss Marcio Rosa during a sun-soaked vacation.

She returned to Twitter.com on Friday (17Oct14) to reveal they have already tied the knot, sharing a picture of their wedding bands and a piece of paper bearing her married name.

She writes, "Sorry for the sudden announcement but I am officially Mrs Sousa Rosa!!! ImMarriedYa'll!!! yay blessed so happy."
