'Basketball Wives' Star Tami Roman Sued for Bailing on Hair Endorsement

"Basketball Wives" star Tami Roman signed an endorsement deal with a line of hair extensions in which she promised to feature the product on her show -- but a new lawsuit claims she not only didn't deliver on that promise ... but she featured her own hair line on the show instead!

According to a lawsuit filed earlier this month in Texas, Roman agreed to become a spokesperson for Crème De La Crème Hair. In the lawsuit, Crème says part of the deal called for Roman to "have an appearance on VH1's 'Basketball Wives' where she will discuss her hair line with the [Crème's] owners."

But according to Crème, Tami bailed on every attempt they made to coordinate their appearance on the show.

The final straw for Crème came last month when Roman was supposed to promote Crème at a hair show in Atlanta. They claim Roman showed up as planned with a "BB Wives" film crew ... but was there promoting her OWN line of hair in competition with Crème. They also claim Tami's manager instructed the crew not to film anything Crème.

Crème is suing for damages in excess of $75,000 and they want the footage shot for "BB Wives" pulled from the show unless it's edited to feature them.
