Bristol Palin is demanding full custody of her son with former beau Levi Johnston.

The teen daughter of former GOP VP candidate Sarah Palin has launched a bid against the buffed-up beefcake in open court for sole control of their infant son.

An Alaskan judge revoked the pair’s anonymity in court proceedings over the fate of their 1-year-old son Tripp last week, revealing details of the case for the first time, The Associated Press reported Tuesday.

“The best interests of the child compel the conclusion that Bristol should be awarded 100% legal and physical custody of Tripp, with visitation rights in favor of Levi,” Bristol’s attorney Thomas V. Van Flein said in the papers.

“I do not feel protected against Sarah Palin in a closed proceeding,” Johnston had said in an affidavit obtained by The AP. “I hope that if it is open she will stay out of it. Bristol’s attorney is her attorney.”

He added, “I feel more comfortable in a public courtroom which will help everyone stay civil and be on their best behavior.”

Bristol Palin argued “no good could result to the child by an onslaught of media.” The 18-year-old petitioned for sole custody and financial support of Tripp, in court papers filed in November

Her petition calls her former high school sweetheart’s recent nude photo shoot with Playgirl “risqué” and She demands that Johnston’s mother — who is serving a 3-year prison sentence on drug charges not be allowed unsupervised visits with Tripp.

Palin also accuses Johnston of skipping visitation with his son and possibly abusing marijuana — citing “weed” references on a Twitter feed that bears his name.Johnston says the Twitter account is a “fraud” and also denies snubbing the child.

He is seeking shared custody.
