Singer/songwriter Alicia Keys has publicly congratulated rapper Jay-Z and his new wife Beyonce Knowles, who were married in a top-secret ceremony last week.

Although the couple's representatives have yet to confirm the wedding took place, it has been reported Jay-Z, real name Shawn Carter, and Knowles exchanged vows on Friday evening and then threw a lavish party at the rapper's TriBeCa apartment in New York.

And Keys couldn't be happier for the newlyweds.

She tells OK! magazine, "All the best wishes possible, and I think that love is beautiful and when you love somebody, just let it shine and shine bright."

Keys is the second star to extend warm wishes to the couple. Mary J. Blige offered her congratulations to Jay-Z, her current tourmate, at a concert on Saturday, before launching into her hit song "You're All I Need."
