New court documents reveal a heated custody battle between Sarah Palin's daughter, Bristol, and her Playgirl model baby-daddy Levi Johnston.  The first win, however, goes to Johnston.

A judge has ruled that the custody battle for the couple's baby, Tripp, will be open to the public.  Bristol and the Palin's wanted the proceedings to take place behind closed doors.

"Levi is not yet mature enough to take on significant parental responsibilities," Bristol says in her petition, the Anchorage Daily News reports.

Johnston wants it all out the open, so that a certain former Vice-Presidential contender can't manipulate the situation.

"I know that public scrutiny will simplify this matter and act as a check against anyone's need to be overly vindictive, aggressive or malicious, not that Bristol would ever be that way, nor that I would," Johnston writes in his affidavit, according to the Daily News. "But her mother is powerful, politically ambitious and has a reputation for being extremely vindictive."

He added, "...So, I think a public case might go a long way in reducing Sarah Palin's instinct to attack."

Bristol Palin insists her mother is not involved in the case.
