Rihanna is being sued by a funeral company in Barbados after allegedly failing to pay up for grandmother Clara Braithwaite's lavish send-off

Superstar Rihanna is being sued for $150,000 by a funeral directors in Barbados after allegedly failing to pay the bill for her grandmother's lavish send-off.

The 25-year-old singer's maternal grandmother, Clara Braithwaite, died from cancer in June 2012 and her body was sent to Barbados for burial.

According to court documents obtained by celebrity website TMZ.com, the Diamond hitmaker wanted to lay Braithwaite to rest in grand style and organise a wake complete with tents, multimedia screens and huge floral arrangements .

Lawyers for the funeral home claimed that the party cost more than $150,000 but RiRi paid only about a quarter of that and refused to pay more.

The plaintiff is seeking at least $150,000 (£100,000) to cover the loss of profits.

Rihanna shared a close relationship with her grandmother and was often pictured by Braithwaite's bedside during her battle with cancer.

In the wake of her death, Rihanna cancelled concerts and paid tribute to her on Twitter. she wrote: "Goodbye grangran Dolly, get your beauty rest until I see you. GrangranDolly that is all."

Rihanna has not responded to the funeral home's allegations.
