Britney Spears says she couldn’t get ‘messed up’ like Christina Aguilera

The “Overprotected” Britney Spears claims she couldn’t party like the “Dirrty” Christina Aguilera.

The “Overprotected” singer, 41, recalled not being able to drink like the “Dirrty” songstress, 42, circa 2012 due to her highly publicized conservatorship in her new memoir “The Woman in Me,” which was released Tuesday.

“The tours under the conservatorship were strictly sober, so we weren’t allowed to drink. Once, I ended up with most of the same dancers as Christina Aguilera. The dancers and I met up with Christina in Los Angeles. She seemed pretty messed up,” Spears wrote.

“But the dancers and I wound up swimming in a beautiful pool and sitting in a Jacuzzi. It would have been nice to have drinks with them, to get rebellious, sassy, fun. I wasn’t allowed to do that because my life had become a Sunday-school Bible church camp under the conservatorship.”

The Post has contacted reps for Aguilera for comment.

Spears also accused her “horrible” father, Jamie Spears, of forcing her to check into rehab during her “Piece of Me” Las Vegas residency after her then-boyfriend Charlie Ebersol introduced her to energy-boosting supplements without Jamie’s permission.

“My father didn’t like that. He knew what I ate; he even knew when I would go to the bathroom. So when I started taking energy supplements, he saw that I had more energy onstage and that I was in better shape than I had been,” she wrote.

Elsewhere in the book, Spears praised her former “Mickey Mouse Club” co-star for being “really professional” on TV, specifically on “The Voice” as the “Toxic” singer admitted she “absolutely hated” her time on the judging panel of “The X Factor.”

Aguilera appeared on “Jimmy Kimmel Live” last week where the funnyman asked if Spears gave her any warning on whether she’d be mentioned in the book.

“I don’t know! I don’t know,” Aguilera said, claiming she had not heard from her fellow pop icon. “Am I hoping? I mean, I’m hoping that, you know, everything is all good with her and everything’s beautiful. I think the future should be celebrated.” 

“Maybe you will be in it,” Aguilera told Kimmel. “Let’s put it this way: I’d rather it be you than me. So hopefully you’ll be in it. You’ll make the book.”
