Doubts have been cast over actress Sheridan Smith’s return to West End production Funny Girl, after show ­bosses failed to confirm when she would be back on the stage. The 34-year-old was expected to make her stage comeback today after being given “two to four weeks” off last month due to “stress and exhaustion”.

A source told The Sun: “Sheridan was expected to be back for this weekend. The fact this has not happened is very worrying. Her time off was meant to refresh her batteries and get her head straight. But clearly it’s not worked and bosses feel she’s not ready to return.”

In May show bosses confirmed Sheridan would be taking a break from the show, after she pulled out of a series of performances. A statement from the show read: “Sheridan Smith will be taking leave of absence from Funny Girl, due to stress and exhaustion”.

The actress' leading role as Fanny Brice has since been played by Natasha J Barnes, who has impressed fans and critics. But speaking to The Telegraph in May Barnes said the production wasn’t the same without without Smith.

“This is absolutely the pinnacle of my career,” Barnes said. “But because Sheridan’s a friend and we’re a family, it’s never going to feel whole without her here. When I’m on stage I don’t have time to consider it but backstage before and after the show there is this absence. I miss her and worry about her and I hope that she’s alright.”
