By Tuesday, Paris was back at work on her sophomore album, clocking even more hours in the studio. Judging by her tweets, she's been productive: "Just finished recording another song! #YES! On to the next one! :D"

Paris has hinted that her new album, which reportedly features collaborations with longtime pals LMFAO and Snoop Dogg, will be significantly different from 2006 album Paris. She told Page Six that her boyfriend Afrojack is her executive-producer. Mixing business with pleasure: Always fun!
