In her new psychological thriller, Sleepwalker, Panettiere, 36, explores the question of how much a mother can endure as mourning mom Sarah, whose grief after losing her daughter [\u2026]\t\t<\/p>\n<\/div>\n Panettiere and Ventimiglia originally got together in 2007 before going their separate ways in February 2009. At the time, a source exclusively told Us<\/em> that there was \u201ca lifestyle conflict\u201d and that the Heroes<\/em> costars were in \u201cvery different places.\u201d<\/p>\n Looking back on that tumultuous time, Panettiere shares with Us<\/em> that the final days of her relationship with Ventimiglia were hectic, as he broke up with her and then immediately took her back when she started \u201chysterically\u201d crying. The two ultimately split for good a short time later.<\/p>\n Asked whether she thought Ventimiglia only took her back because of her tears, she admits to Us<\/em>, \u201cOne hundred percent it was only because I was over the toilet, hysterically crying. It was like my world had crumbled.\u201d<\/p>\n \u201cIt was so out of left field, nothing that big or explosive had happened. Nothing had really gone wrong. Nobody cheated,\u201d she points out. \u201cI remember the look on his face being pure shock at how visceral and massive my negative reaction was, and he immediately took it back.\u201d<\/p>\n Panettiere met boxer Wladimir Klitschko<\/strong> not long after splitting from Ventimiglia and they were ultimately together on and off from 2009 to 2018. (They welcomed a daughter, Kaya Evdokia Klitschko, in December 2014.)<\/p>\n The Nashville<\/em> alum officially comes out as bisexual in her memoir, revealing that she never felt comfortable discussing her attraction to women until recently.<\/p>\n You have successfully subscribed.<\/p>\n<\/p><\/div>\n<\/div><\/div>\n \u201cIt was always the fear of not being perfect, and what my team was going to think about it, what the public\u2019s opinion was going to be about it,\u201d she tells Us<\/em>. \u201cIt was just never the right time, and it was a very difficult topic to articulate properly. I wanted to make sure that I really sat down and chose my words carefully and was able to tell my story in an honest way, that people understood. On one hand, it\u2019s sad that I had to wait till I was 36 years old to share that part of me, but better late than never, right?\u201d<\/p>\n
