ITV's This Morning viewers were left 'worried' after Alison Hammond suddenly vanished off-screen.
Co-presenter Dermot O'Leary was left to present the show alone after Alison rushed off while appearing to hold her chest.
Following an advert break, Dermot then told This Morning viewers: "Alison is feeling just a little unwell. She's had to duck out and she will hopefully be back."
No other details were confirmed, but viewers quickly took to X to share their concern.

Later in the show following a second break, Dermot then confirmed he would be holding the fort for the rest of the show and that Alison would not be returning due to feeling 'unwell'.
Following the incident, faint shouts could be heard in the background.
Dermot quickly escorted Alison, 51, off screen during a segment with vet Dr Scott Miller who was taking call-ins about dogs and their troublesome behaviours.
Dr Miller looked visibly concerned before Dermot returned and the pair tried to resume their chat normally.
"Very weird I hope she's ok she sounded awful," one viewer commented. "What on earth has happened with Alison? Hope she's okay," a second posted.
A third questioned: "What just happened to alison hammond?" as a response read: "I wondered the same?! Frightening."
After Demot confirmed that Alison wouldn't return for the rest of Friday's show, viewers quickly shared well wishes for the presenter.

"I am very worried about Alison, I hope she is ok, she's a great presenter, I love her," one person penned on X.
"Dermot looks very worried," said another.
Alison is a regular contributor on This Morning and became a familiar TV face after she rose to fame on Big Brother in 2002.
She has also made appearances on the likes of Strictly Come Dancing and is now host on the Great British Bake Off and For The Love of Dogs.
