And there's more baby mama drama on the horizon for Heat baller Chris Bosh.  He's playing in one of the biggest series of his career, and he wants his daughter to be able to take part.

But her mama Allison Mathis isn't trying to have it.  Deets on Allison and Chris battling out custody, and Allison not allowing their daughter to attend the Finals games, when you read on....

Chris Bosh and his ex-girlfriend Allison Mathis have been going through a hard core custody battle.  If you recall, the two have been through all types of drama including stalking accusations and just all around crazy baby mama ish.  And they're currently abiding by a temporary shared custody set up, and Allison currently has their little girl, 2-year old Trinity.

Chris sent Allison an email pleading for her to allow Trinity to come to his game now that he's in the NBA Finals.  And she refuses to respond.

The email, copped by TMZ, shows Chris asking Allison to allow Trinity to attend his games as this is a very important tome in his life.  Chris apparently showed the email to the judge in their case, in an attempt to show he tried to work something out on his own without involving the courts. And he's currently waiting to hear back from the judge.

Thankfully, Chris takes his share of custody on June 11th--right before Game 6.  So Trinity will probably be at a game afterall.
