Beyonc Knowles and rapper husband Jay-Z celebrate their four-year anniversary today amid reports that they are set to renew their vows.

The couple tied the knot in 2008 but they have been together over 10 years.

An insider told Star magazine that the proud parents of three-month-old Blue Ivy are more in love than ever and want to solidify their union with another trip up the aisle.

The 42-year-old music mogul apparently "came up with idea."

"Jay told Beyonc earlier this year that he wanted to marry her all over again," a source told the publication.

"They want the ceremony to be simple but elegant. They're having Nobu cater it, and Jay put together a special presentation showing him and Bee through the years."

The event is set to take place at the couple's estate in Scarsdale, New York this month with close friends Gwyneth Paltrow, Chris Martin, Kanye West and Oprah Winfrey in attendance.

Beyonc will also reportedly invite her estranged father Mathew Knowles to the event because she "doesn't want any more bad blood" between them.

Photographs from the couple's first wedding have never been released although they reportedly said "I do" in their Tribeca home.
