Last year, Shanna spoke openly about getting liposuction on her chin, arms, thighs and stomach and tells In Touch, she's not embarrassed by the work she's had done. "There’s no reason to be ashamed. I live an active, healthy lifestyle — I work out and do yoga — but had a pooch on my tummy from three C-sections. No amount of crunches would make it go away."

Any other plastic surgery for Shanna? "I’ve been doing Botox since I was 28, but no real surgery on my face. And my breasts are real."
