Hip-hop mogul Shawn ‘Jay-Z‘ Carter has reportedly proposed to his long-term girlfriend, Beyonce Knowles. According to British media reports, Shawn Carter canceled several U.S. promotional appearances for his Roc-A-Fella empire and flew out to France last week to surprise the Ms. Knowles with a romantic break in Cannes, where he allegedly popped the question.

Beyonce – who is currently in the U.K. as part of her world tour – accepted the proposal, and a source says the rapper has promised her “the biggest diamond she can fit on her finger”. The source adds, “This will be the hip-hop wedding to end all hip-hop weddings.”

Earlier this year, the former Destiny’s Child star gushed about her romance with Carter, saying: “I want to get married and really want a family – in a perfect world I’d have two boys and a girl. You know someone loves you by the way he treats you and respects you. Me and Jay respect each other.”

The couple are said to be planning to marry in Hawaii later this year.

A lawsuit has been filed against Beyonce Knowles by The Royalty Network. The suit, which also names Beyonce’s company B-Day Publishing, is taking place in a Manhattan Federal Court, over the song “I’m Kissing You.”

The song, which was originally performed by singer Desree and featured in the updated movie version of Romeo And Juliet‘, was written by Timothy Atack and Desree. The lawsuit claims that Knowles violated the copyrights of Westbury Music, which is administered by The Royalty Network. Also named in the lawsuit are Columbia Recording Corp., Sony BMG Music Entertainment and EMI April Music.

Desree is best known for her 1994 hit single “You Gotta Be.” Beyonce covered “I’m Kissing You” on the re-release of her album B’Day.
