Heat Player Chris Bosh Sued By Baby Mama "He's Blocking Me From Being On Basketball Wives"

After losing the NBA Finals Christina Bosh is possibly embarking on another lost.  Bosh is being sued by his baby mama -- for allegedly F**cking up her deal to join the cast of "Basketball Wives" ... AFTER she signed her contract.

Bosh's ex -- Allison Mathis -- filed the lawsuit in Orlando, FL earlier this week ... in which she claims she signed a deal with show producers which could have scored her more than $250,000 for at least 4 seasons ... but Chris screwed it up. Rumor has it he's a "down low brotha" and was afaird his double life although he's married someone else might be revealed.

According to the docs, Bosh lied to producers -- and told them Allison had too much court drama and as a result it prohibited her from appearing on camera. Bosh also allegedly threatened to sue producers if they put her on the show.


Mathis claims the producers folded like a cheap suit -- and axed her from the show ... after she had already taped two episodes.  In the lawsuit, Mathis also includes a copy of her contract -- which shows she was slated to make $2,500 per episode for the first five shows ... and $5,000 for each additional episode. Bosh and Mathis share joint custody of their daughter.
