Hayden Panettiere is back.

The "Nashville" star, 26, made her first public appearance since entering treatment for postpartum depression in early October, stepping out to support fiance Wladimir Klitschko, 39, during his hugely hyped world heavyweight title fight in Dusseldorf, Germany, on Nov. 28.

Hayden, 26, looked happy and healthy as she posed for photographers wearing a striped sweater, plaid miniskirt and hat before Wlad's bout with Britain's Tyson Fury. At one point, she cheered on her fiance while draped in the yellow and blue flag of his native Ukraine.

But that show of solidarity wasn't enough: Tyson beat Wladimir, marking the Olympic gold medalist's first defeat in 11 years.

As a bruised and bloodied Wlad left the arena, Hayden was by his side where she could be seen holding his hand while wrapping her other arm around him.

Hayden, who gave birth to their daughter Kaya in December 2014, first spoke of her struggle with PPD in September. "It's something that needs to be talked about," she said during an appearance on "Live! With Kelly and Michael." "Women need to know that they're not alone, and that it does heal… It's something that's completely uncontrollable. It's really painful and it's really scary and women need a lot of support."

Just days later, her rep announced that the actress was seeking in-patient care as she struggled to cope with the condition. "Hayden Panettiere 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," read the statement.
