Britney Spears just released her newest, eighth studio album Britney Jean on November 29. And in the January 2014 cover issue of InStyle magazine, the popular songstress talks about MUCH more than just music!

Like the fact that she hit=up renowned Beverly Hills plastic surgeon Dr. Raj Kanodia for some plumpy lip injections:

"A doctor I see, Dr. Kanodia, does fun stuff to me sometimes - I've had lip injections before. He has this peptide-based face-care product; it's green and slimy, and you mix it together and put it on your face. It does wonders. You leave it on overnight."

Although Spears admits to getting some plastic surgery, the 32-year-old singer thinks "it's cruel how the world puts so much emphasis on our looks." Look at the criticism poor Kim Kardashian went through while pregnant:

"I see Kim and what she went through when she was pregnant - the tabloids were so mean to her because she was big," says Spears. "At one point in the show she was upset and said something like, 'I would be lying if I said that the criticism from the paparazzi while I've been pregnant hasn't taken a toll on me.' And I was like, 'Bless her heart,' because I remember that time," Spears reveals to InStyle. "First of all, you are already emotional, and then the paparazzi are taking pictures of you pregnant. That should be the time when your body is the most treasured."

Speaking of pregnancy... what's one of the best things about being with child? The sex, of course!

"I loved being pregnant for so many reasons," she says. "Not to mention the sex is awesome then."

Awesome.
