Ukraine.<a href="

After she broke up with Klitschko, she started dating Brian Hickerson. In 2020, they broke up after he was arrested for corporal injury on a spouse/cohabitant, assault, and intimidating a witness (Panettiere). The charges stemmed from alleged incidents between May 2019 and June 2020.<a href="

Panettiere publicly came out as
bisexual in 2026.<a href="
https://en.wikipedia.org/wiki/Hayden_Panettiere#cite_note-83"><span><span>[</span>83<span>]</span></span></a>"That's something about me I was never able to share with the world, because it was just never the right time...Then came the period where it felt like people coming out, especially women, saying that they were bisexual or liked girls, was a fad. I was afraid that if I was honest, it was going to be like me jumping on the bandwagon. It was a very difficult topic to articulate properly," Panettiere said in a Us Weekly article. "It's sad I had to wait until I was 36 years old to share that part of me, but better late than never, right?"
Speaking on why she remained closeted until age 36 and whether she had relationships with women, Panettiere stated, "Yeah, I did. It was scary, though, because there were
paparazzi always waiting for me outside, to follow me everywhere. I had very little privacy. I have dated women. I was much more into women even as a child than I was men. I have explored it, but because I hadn't shared this with anybody, I didn't really have the courage to throw myself fully emotionally into it. Because then if I did fall in love, that wasn't something that I wanted to ever have to hide."<a href="
