Pamela Anderson and ex-boyfriend Laurence Hallier are engaged in a legal battle over a Las Vegas condominium endorsement.
The former Baywatch actress reportedly signed a deal in 2006 to make a series of promotional appearances for Hallier's Panorama Towers high-rise luxury homes in exchange for a condominium of her own.
Anderson eventually filed a $1m suit against her former lover, claiming that Hallier was unable to secure her a dwelling at the Panorama Towers and had agreed to pay her the sum in return.
Hallier has now alleged in his own countersuit that Anderson failed to live up to her endorsement agreement by refusing to make several public appearances as stipulated in her contract, TMZ reports.
He is contending that Anderson's failure to promote Panorama Towers resulted in a significant loss of sales and is seeking $22.5m in damages from the star.
A rep for Anderson has declined to offer any comment.
Laurence and Anderson apparently dated on and off for several years, before finally spitting in 2010.
