MOM JUMPS ON BRITNEY BANDWAGON!

BRITNEY SPEARS’ mother, Lynne, is jumping to her daughter’s defense — and slamming her ex-husband — in recently filed court documents!

As the “Toxic” singer’s new hotshot lawyer, Mathew Rosengart, filed a petition to remove Britney’s dad, Jamie, as her conservator after 13 years, Lynne branded her former spouse a louse — and told the court, “He is incapable of putting my daughter’s interests ahead of his own.”
