The 29-year-old songbird was in a rather cheerful mood as she ran into the paparazzi, even at one point turning the camera on them.
Clutching her phone in one hand and a bottled water in the other, Christina looked hot in her white jeans and leather vest as she enjoyed an evening off mommy duty.
Following her night out, she tweeted: “Sleep well friends-dream BIG tonite-and live up to them tomorrow.”
Meanwhile, Christina is rumoured to be joining next season’s Dancing with the Stars cast.
The thirteenth season of ABC’s hit dancing competition show has an all-star line-up. And even a Kardashian.
The names that have previously been linked to the upcoming season include Queen Latifah, Jersey Shore star Nicole ‘Snooki’ Polizzi, Tiffani Thiessen and Rob Kardashian.
