Shawn "Jay-Z" Carter and Beyonce Knowles are now husband and wife, a close friend of the couple has revealed.

The couple is alleged to have married in a private ceremony at a chapel in Scarsdale Village in Westchester, New York, last Friday afternoon, surrounded by around 30 friends and family.

The all-white ceremony was attended by Knowles' mother Tina and father Mathew, and her younger sister Solange. Also in attendance were the Crazy In Love star's former Destiny's Child bandmates, Kelly Rowland and Michelle Williams, Carter's mum Gloria, and pals Chris Martin and Gwyneth Paltrow.

The wedding party then moved on to the rap mogul's luxury New York penthouse apartment in the TriBeCa area of the city, where a marquee had been erected on a terrace at the building. The marquee was also decorated with five-foot tall candelabras and 60,000 elegant white orchids, which had been flown in from Thailand at a cost of $US500,000.

The wedding reception was reportedly attended by more than 200 guests, including producer/music mogul Jermaine Dupri and his girlfriend Janet Jackson, R&B singer Usher, rappers Wyclef Jean and Kanye West, producer Pharrell Williams, and Knowles' Dreamgirls co-stars Jennifer Hudson and Jamie Foxx.

The couple is reportedly set to honeymoon at a luxury $8,000-a-night hotel on the Caribbean island of Anguilla later this
year.
