Christina Ricci is tired of partying, femalefirst.co.uk reports.

The actress admits she can’t keep up with the pace of her friends and likes to be tucked in bed at a reasonable hour so she can get her sleep.

“I’m always in bed by 11 or 12 and people laugh all the time — they want me to hang out until two in the morning, but no, I need my nine hours.”

The 28-year-old also said she needs to start paying more attention to her diet now that she is getting older.

“I eat crap. I’m an inconsistent eater — all things you’re not supposed to be. I forget to eat, then I’ll eat a bag of potato chips. And then you get to a point at a certain age when you’re like, ‘All right, I guess I have to take care of myself now.’

“I’m a lazy, lazy girl. But I figure I’m so high-strung that I probably burn some calories in nervous energy.”
