Amy Schumer is suffering from hyperemesis gravidarum.
The Trainwreck actress is expecting her first child with husband Chris Fischer and has been forced to cancel a show in Texas as she's been hospitalised due to extreme morning sickness.
Amy posted her apologies on Instagram but reassured her fans that she's being well taken care of and her baby is doing "fine".
She wrote: "Texas I am so deeply sorry. I have been really looking forward to these shows. I have to reschedule.
"I am in the hospital. I'm fine. Baby's fine but everyone who says the 2nd trimester is better is not telling the full story. I've been even more ill this trimester. I have hyperemesis and it blows.
