Chris Bosh just won his second NBA championship in a row as a member of the Miami Heat. While that’s a cause for celebration, the NBA All-Star is also in the midst of some serious baby mama drama. 

Reports TMZ:

Newly-minted NBA champion Chris Bosh has been busy with more than just basketball … he’s been embroiled in a bitter legal battle with his ex to snag custody of their 4-year-old daughter, TMZ has learned.

Bosh has filed legal docs asking a judge to strip his ex, Allison Mathis, of primary physical custody of Trinity.

Bosh claims Mathis has been trying to alienate the kid from him … blocking contact, refusing to let them travel together, and poisoning their daughter against him.

Bosh wants primary physical custody, but says he’s more than willing to give Mathis her fair share of mother-daughter time in the form of visitation.

Mathis has fired back in her own legal docs, saying his complaints are BS.

The custody battle between Bosh and Mathis has been raging for years — you’ll recall, just last June Bosh was denied permission to take his daughter to the Olympics.

But hey, at least he’s got another championship ring.

Chris Bosh is married to Adrienne Williams-Bosh, and the two have a daughter named Jackson that was born during last year’s playoffs.

There are few things worse than a woman using a child as a bargaining chip with a a man Let’s hope Bosh and his ex work things out.
