Alicia Keys will marry her music producer boyfriend Kerry 'krucial' Brothers in New York this summer, according to reports.

American magazine Star claims the couple has booked Oheka Castle on Long Island for a ceremony on Independence Day - July 4th.

Bosses at the 32-bedroom French-style chateau have confirmed a wedding will take place that weekend, but have refused to reveal the identity of the bride and groom.

Keys and Brothers have never spoken openly about their relationship. They have been songwriting partners for years, co-owning the KrucialKeys production company and New York's Oven Recording Studios.

A representative for the R+b star has yet to confirm or deny the wedding reports.
