Out of fear of catching COVID-19, actress Liv Tyler has quit Fox’s 911: Lone Star. Though she had had a multi-year contract, she asked to get let out after just one season.

Tyler has expressed concerns about the pandemic before – at its start in April, she made in Instagram post about how coronavirus had flipped the world upside-down.

Thank you 🙏🏻💗🙏🏻💗to everyone who is giving their everything to protect us all. To wake up everyday and fight this monster head on. Thank you for your love and care and not giving up. To everyone still working to keep us all alive , fed and society supported on a daily basis , bless everyone staying home in various quarantine situations. It is challenging for all in many different ways. I’ve been overwhelmed myself with what’s happening. Trying to digest it all and protect my children. I had to take a breather from the pressure and normality of what was our reality before this virus hit us . We are now forever changed in so many ways. @davidgardner and i have 4 children ages 3,5,12,15. We have been in quarantine for 20 days. 🥴😬🙏🏻💗🙃 Omg taking care of 4 kids not in school is no fucking joke. Bless all caregivers🙌🏻24/7 cooking , cleaning , school, love , play , listening, more cooking , more cleaning and again. My hands are raw as so many’s are. I have been trying my best to keep my family going as normal. The news / tv is so painful everyday. So many suffering. What can we really do to help? We are told to stay home but my heart wants to check in on everyone. Im very moved by the work still going on. The medical teams , scientists , all hospital workers , world leaders and everyday important workers keeping it all going. The little details mean everything. Thank you!!!! I hope you can feel our deep gratitude and know you are appreciated and supported. Who knows what is going to happen? This is a whole new fucking world 🙈What will life be like after all this ? We must believe in each other. In Mother Nature, In humanity , hold ourselves and our loved ones close in our hearts. I woke up this morning and this woman @sydvic1ous inspired me so much I broke out of my fear cacoon. I was in pure momma bear survival mode trying to care for my family . But my children’s love and laughter is so healing and humor between friends the greatest relief. Thank you thank you thank you to all the brave souls keeping it all going and risking their health and lives for us. Praying for safety and support for all. With love and a million hugs. Xoxox

Now, the star has left the first-responder drama since the show is shot in the United States, and she fears flying back and forth between her home in the U.K. and the filming locations. The U.S. also currently has the highest total coronavirus cases and deaths in the world.

Tyler’s character, Michelle Blake, will not be recast or killed off. In a statement by the showrunner, Tim Minear, it was announced that her story has simply come to a close.

“What a thrill it was having a movie star of Liv Tyler’s stature to help us launch the first season of 9-1-1: Lone Star,” Minear said. “We loved working with Liv and will be forever indebted to her for her haunting, powerful portrayal of Michelle Blake. While we were able to tell a complete chapter in Michelle’s story, as with Connie Britton on our mothership, we also feel like there are more stories to be told. The door here will always be open for a return.”
