Mariah Carey is known as a workaholic, but the pop diva can only record her albums in the middle of the night.
Mimi is currently working on her upcoming album Memoirs of an Imperfect Angel and took to her twitter page to keep her fans updated on the status of her work.
Mariah wrote on her twitter, "In the studio? driving the engineer crazy cos I'm a control freak and once again we're STARTING at 1:16 am..perfectly normal: ) (sic)"
Two hours later she posted another update proving she was still up and working. "still in the studio. Hopefully I'll finish this one tonite. It has a lot of bv's and I'm doing them but you know I like that mess. (sic)"
She finally called it a day at 4:15am and went into the kitchen to "play with the dogs."
Mariah is certainly on a roll lately. She's getting critical acclaim for her movie roles lately and her new album is said to be one of her best work to date. Can't wait for the new album!
