Britney Swings Both Ways?

Party mom Britney started the weekend by taking son Sean Preston to a park in Beverly Hills for some quality mother/son time, playing around on the slides and pushing the kiddo on the swings. Is time with her quality?

Once playtime was over, Spears shifted into partying overdrive by heading to popular gay hangout The Abbey in West Hollywood, where she spent the evening with new boytoy Isaac Cohen.

Sin City was Brit's last stop on her non-stop weekend partying, where, according to EXTRA's Las Vegas Bureau, she began the evening at the new hotspot Social House inside Treasure Island, where her and a group of six friends took in some fine fish and dessert.

From there, Brit headed over to the provocative Cirque de Soleil show "Zumanity." Once the group finished the show, Brit was just getting started. She made her way to the tourist trap Coyote Ugly bar inside the New York New York hotel and casino, where the pop tart was coaxed into dancing on the bar with the bartenders. After working up a sweat at Coyote, it was off to ultimate Vegas hotspot Pure, where Britney and pals danced on the VIP main stage to the wee hours of the morning.

Ah, the life of a young mother.
