Kevin Federline and his lawyer will be in court on Thursday for an emergency hearing regarding the custody issue between him and former pop star Britney Spears.

“Our best information is he will be here; she won’t,” said Parachini. “But anything is possible.”

Federline filed papers seeking spousal support and sole custody of the children after Spears sought to end their two-year marriage last November. A temporary court order issued Feb. 1 granted the couple joint custody until the end of this month.

Parachini said Federline’s lawyer would try to persuade a Superior Court commissioner that the matter is urgent enough to be handled on an expedited basis.

Britney’s odd behavior over the past two weeks could come back to haunt Spears where she fears most…custody of her two small boys.

Popping in and out of rehab centers around the world is not a smart move for someone involved in a child custody battle with her estranged husband, said New York-based family law attorney Joshua Forman, who is not involved in Spears’ case.

After leaving Promises on Wednesday, Spears attempted to keep a low profile but the celebrity Web site TMZ.com posted video of her wearing a wig and leaving what it said was a lawyer’s office.

Reverend Billy Graham would have a hard time getting custody of Brit’s kids if they had been married because the courts so heavily lean towards giving custody of children to the mother. When you add to the fact that Kevin Federline is not Billy Graham it makes it that much less likely that he will be able to obtain custody of Sean and Jayden. Someone who could file a petition and possible be granted temporary custody of the children is Britney’s mother. That would basically just be a legal maneuver with the wide-held belief that her mother has the children the majority of the time as it is.
