Lopez signed a deal to promote the hoverboards in late 2015, at the peak of the hoverboard fad.
The Let’s Get Loud singer did tweet about the hoverboards once. On May 26, 2016 she posted a video of her dancers performing on the boards while she sang Love Don’t Cost a Thing in the centre of them.

Under the agreement, Lopez was supposed to post about the hoverboards at least once every three months on the two social media platforms.
The lawsuit says that the hoverboards were selling for US$1,295 each at the time of the agreement. The suit seeks damages of US$54,390 or the retail value of 42 hoverboards.
The same company threatened to sue Richard Sherman of the Seattle Seahawks a year ago, claiming he also went back on his agreement on a promotional deal.
The popularity of hoverboards began to decline after the risks surrounding them were widely documented.
Many hoverboard owners have documented faulty self-balancing scooters bursting into flames.
WATCH BELOW: Hoverboard warnings
In December, Amazon pulled many popular hoverboard models from its website after authorities around the world issued warnings about the safety of the devices.
Many airlines, including Air Canada, have barred travellers from bringing them on board planes.
Also in December, more than 15,000 hoverboards were seized by U.K. officials due to safety concerns.
According to the U.K.’s National Trading Standards board, officials found many concerns surrounding the plugs, cabling, chargers, batteries, or the cut-off switch within the boards, which sometimes fails.
