Hayden Panettiere made her first appearance since revealing her battle with postpartum depression, by attending her fiance's boxing match in Germany.

A spokesperson for the Nashville star announced in October (15) that she had admitted herself into a facility for treatment after she was diagnosed with depression following the birth of her daughter Kaya in December last year (14).

Wearing a mini-skirt, pink sweater and fedora, Hayden appeared ringside at the boxing match in Dusseldorf on Saturday (28Nov15) to support her fiance, former heavyweight boxing champion Wladimir Klitschko.

Despite Wladimir losing his nine-year championship reign to British boxer Tyson Fury in the match on Saturday, Hayden looked healthy and happy as she posed for photographers with the flag of her fiance's home country, Ukraine, draped around her shoulders.

Hayden, who got engaged to the boxer in October, 2013, revealed her battle with postpartum depression while on Live! With Kelly and Michael in September (15).

She says, "It's really painful and it's really scary and women need a lot of support. It's something a lot of women experience. When (you are told) about postpartum depression, you think it's 'I feel negative feelings towards my child; I want to injure or hurt my child.'

"I've never, ever had those feelings. Some women do, but you don't realize how broad of a spectrum you can really experience that on."

Coincidentally, her character on Nashville is also dealing with the condition. It was announced Hayden would be taking a break from filming the show while she received treatment for her depression.

Her spokesman said at the time, "(She) is voluntarily seeking professional help at a treatment center as she is currently battling postpartum depression. She asks that the media respect her privacy during this time."
