Ellen DeGeneres and James Corden have suspended their TV shows due to fears over the Covid-19 pandemic.
The virus has caused chaos in Hollywood, with a large volume of film and TV production halted in an attempt to stop the illness spreading.
Apple, CBS, Disney and NBC are among the major companies who have suspended production on some of their projects.
Announcing work on The Late Late Show with James Corden was also being paused, Corden tweeted: "After much deliberation we've decided to suspend The Late Late Show for the time being.
"We really explored every option to try and put a show on for you, but right now feel the safest thing to do is to stop for a moment and take advice further down the line. Stay safe out there x x"
DeGeneres said she is "already bored" as production on her chat show was suspended.
The news comes a day after producers said DeGeneres would continue to film but without a live studio audience.
She revealed the full suspension on Twitter.
DeGeneres said: "Hey there. Me again. So, after some more thought, we have decided to suspend production completely until March 30th.
"We just want to take every precaution to ensure that we do our part to keep everyone healthy.
"I love you guys, and can't wait to come back. I'm already bored."
Hollywood is reeling from the impact of the coronavirus.
Major film releases including Mulan, Fast & Furious 9 and A Quiet Place II have been delayed.
