After briefly spending time with her two boys last night Brit-Brit hit the streets heading over to the Green Door Bar in L.A. for a night full of Halloween fun! Britney looked rather as she rocked a orgasmic hot pink animal print leotard with a cut out mesh-center which sexy displayed her ta-tas and almost firm midriff. Britney and friends started their partying at a house party thrown by Project Runway supermodel Heidi Klum and her husband Seal. After getting the party started at Heidi’s the party troop including her pals Lucy Walsh and Alli Sims celebrated until the wee hours of the morning at the exclusive nightspot.
