Sheridan Smith is one of the country's biggest stars, but she hit the headlines a few years ago for a very public breakdown.

The singer/actress famously suffered with anxiety, and an understandable grief in the months after her father died.

Her struggles meant she was forced to pull out of work at the time, including a stage production of Funny Girl.

And now, in an interview with Stella magazine, the 37-year-old has admitted that a joke from TV’s Graham Norton was one thing that ‘tipped’ her over the edge at the time.

At the 2016 BAFTAs, he reportedly said, “We’re all excited for a couple of drinks tonight. Or, as it’s known in theatrical circles, a few glasses of technical difficulties.” – allegedly, a dig at Sheridan and her performances.

She told the publication, “That tipped me over the edge. I just lost it. I was in unbelievable distress, trying to keep it all together and then a room full of people in my industry were just laughing at me.”

Soon after the comment was made, Sheridan posted a series of now-deleted Tweets, something she now says she has no memory of.

The star confessed, “Honestly, I don’t remember. Drink. Desperation. Humiliation. I fell over the edge.”

During the interview, Sheridan also addressed the topic of whether she’d ever kids with her beau Jamie, whom she is engaged to. The singer admitted that she’s unsure about whether or not she could handle the responsibility of children.

Sheridan said, “Oh God, I don’t know. Yes on the one hand, but then am I actually ready? Could I cope? I have to ask myself serious questions like this.

“My mum tells me she knows I could. She watched me with my dad in the last few days of his life and told me if I could be that caring I would be a perfect mother – but I don’t know. I just know I’m not perfect.”
