Nicole Scherzinger talks about delay on stage after London Show

Nicole Scherzinger is speaking out after a concert of hers in London earlier this month started 45 minutes late.

The singer and actress, 47, told The sun she was “devastated” and “horrified” when she realized fans attending her show at the Royal Albert Hall on October 6 had to wait so long. Scherzinger explained that the delay was largely due to a time confusion.

“It wasn’t until after I finished that I found out people had been sitting there for so long,” she said. “I was devastated and I was horrified, because I thought, ‘Oh my God, I’d be frustrated too if I was told to sit there that long.’ I think they had to be in their seats at about 7:15pm or something, but I thought my show was going to start at 8pm.

Scherzinger added that she was so pressed for time managing all the show details and a meet-and-greet that she didn’t even have a chance to soundcheck all her songs with the orchestra that night.

“I was just so focused on trying to make it the best show I could for the Royal Albert Hall,” she said. “I bust my balls out there to make sure it’s the best show for everybody. So I thought, ‘OK, if I’m 15 minutes late, then, you know, the most important thing is that I put on the most memorable, best show I can for these people.’

The Tony Award winner went on to show appreciation for his fans as “everyone stopped, and by the end they were up on their feet dancing with me.”

“I want to thank them for their patience and their generosity in putting up with me and I appreciate their understanding,” she said.

Scherzinger’s Royal Albert Hall show was a one-off and was billed as her first major UK solo gig in 13 years. She performed a number of famous show songs and even threw in a few hits of hers Pussycat dolls days, such as “Buttons” and “Don’t Cha.”

The star completed her Broadway debut on Sunset Blvd. in July, a role for which she won the Tony for Best Actress in June.

“I have worked many, many years to build up to this moment, and it has changed my life,” she told PEOPLE of her Broadway success in May. “I’ve never been happier, I think, because I’ve always had so much inside me that I felt people didn’t see or understand. It just feels good now to be able to share it with the world.”
