Rapper Lil' Wayne has been accused of failing to pay a $146,000 jewellery bill.

The star - real name Dwayne Michael Carter Jnr. - is being sued by Jack Sutton Fine Jewellery who allege he failed to pay for a diamond ring and necklace he purchased earlier this month.

The shop filed a lawsuit at Miami-Dade Circuit Court in Florida claiming Carter agreed to pay the bill in monthly installments - but after receiving the first cheque for $24,000 on Oct 12th and a second dated January 2008, the payments were stopped.

Proprietor Jack Sutton says, "I've been doing business with him for at least 10 years. He's always been wonderful with paying me. He spent a lot of money with me. I thought we have a really good relationship. I don't know what happened."

Carter's attorney Ron Sweeney branded the incident a "misunderstanding".

He says, "If, in fact, the allegations are true, then it will be resolved. My client is very responsible."

The jewellery case is the latest in a series of legal trials for Carter - he is currently fighting drug charges in Atlanta, Georgia, gun possession charges in New York and two civil suits in Baltimore, Maryland after several women suffered injuries during his homecoming concert.
