Hayden Panettiere has bid her official goodbye to her depression by letting it rip on “Lip Sync Battle”. She impressed all the judges by doing a “Lip Sync Battle” of “Lady Marmalade” with Christina Aguilera herself. This was also a great opportunity for Hayden Panettiere to work off the remainders of her baby weight gain.

“Hayden Panettiere got a little help from her "soul sister" Christina Aguilera as seen in a teaser for "Lip Sync Battle." On Thursday's installment of the celebrity competition, Panettiere (complete with big hair, red corset, fishnets and bright lipstick) channeled X-Tina's look in "Lady Marmalade" when "The Voice" judge showed up unexpectedly,” according to New York Daily News.

Sounds like “Lip Sync Battle” found another celebrity talent.

If there was any remaining bouts of depression, Hayden Panettiere surely blew it out of her system even before “Lip Sync Battle”. She walked the red carpet of Critic’s Choice Awards with a very sexy outfit that showed off her new curves post baby.

Without her baby girl or her to-be husband Wladimir Klitschko with her on the red carpet, Hayden Panettiere showed the world that she is indeed a sexy mama.

Many people spotted Hayden’s return “to the red carpet, sporting a pale peach Maria Lucia Hohan dress that showed off her figure thanks to the seriously plunging neckline and side cutouts,” according to People.

The actress says that she was inspired by her baby girl Kaya to make full recovery from her postpartum depression.

“I didn't even think about overcoming it. There is no overcoming,” she said according to Daily Mail. “The only important thing to me is that I'm not causing myself pain and discomfort anymore, and I can be a strong woman for my daughter to look up to.”

But she did make a successful return to “Nashville” after her treatment. “Nashville” actress was one of the few Hollywood actress, who was public about her condition and gained a lot praises for doing so.
