Mollie King was rushed to hospital after "collapsing unconscious" in her bathroom.
The Saturdays singer explained that she had got back from work late, and had gone into the bathroom of her London home to get ready for bed when the incident happened.
Calling it a "huge shock", King wrote on Instagram: "After coming home late from work, I suddenly collapsed unconscious on the bathroom floor at 4am, hitting my head and face as I fell ... I ended up being rushed to A E."
She took to the social media site to share an update to fans after being absent from the BBC Radio 1 show she co-hosts with Matt Edmondson.
King admitted the scary incident had been a "real wake-up call" that she needed "to take some time to get my strength back, not just for my own health but so I can be the best version of myself for my family too".
