Pop singer Jennifer Lopez has been sued by a company that manufactures hoverboards (mini-segways), claiming that the singer hasn’t kept up her end of the deal.

According to TMZ.com, Lopez had bought 42 custom made hoverboards from the Sidekick Group to use at her Las Vegas show recently but instead of payment had asked JLo to make promotional posts on her Instagram or Twitter accounts once every three months. The company alleges that Lopez only made one such post but later deleted that too.

The company has reportedly sued JLo for an amount slightly higher than the cost of the boards themselves; that bill ran up to $54,390.
