The 23-year-old Nashville beauty opened up to Women’s Health magazine about her struggles which stemmed from an article pointing out her so-called cellulite.
While she is now happy with her figure and has put the negative press behind her, she is not the only celebrity who has battled body demons.
So who else was once obsessed with their form?
Just like Panettiere, British star Lily Allen opened up about her own Body Dysmorphic Disorder – a psychological disorder where the affected person becomes obsessed with a perceived defect of their body – back in 2010.
Before her revelation to Q Magazine in which she called herself “funny looking’”, Allen unleashed a self-loathing rant on her blog about her appearance.
She has since ended her singing career, stepped out of the spotlight and is happily married with one child and pregnant with her second.
With curves like Shakiras it’s hard to believe the 35-year-old had to seek help from a therapist to get over her body image issues. But the Colombian beauty told Fabulous magazine she spent years worrying about what she looked like.
“I wished I was taller, had longer legs, slimmer hips, a smaller bottom, even straighter hair,” she said. “I’m just like all women – we’re born to criticize ourselves.”
Demi Lovato, 20, has made no secret of her suffering and even had a blog on Seventeen magazine’s website called “My Battle With Eating Disorders”.
She entered rehab in 2010 to face her demons and now claims to be on the road to recovery.
While many celebrities have overcome their body addictions or dependencies, for some it was so bad it almost destroyed their lives.
Jamie Lynn-Sigler’s exercise bulimia almost killed her. When she was just 16-years-old – having just landed the role of Meadow in The Sopranos – she dropped to 80lbs after months of purging on exercise.
The 31-year-old sought help and has been a spokeswoman for the National Eating Disorders Association for years.
