Nicole as Grizabella in the musical, Cats, in 2015
Nicole Scherzinger had an on-off relationship with Formula One star Lewis Hamilton for seven years before she spilt from him in February 2015.
It was a tough period, she says, given the length of the relationship, and she was able to get over the heartbreak thanks to Andrew Lloyd Webber's musical Cats. The 38-year-old X Factor judge played the role of Grizabella in the musical.
"I've never shared this with anyone, but during that time I was going through a break-up with my ex that I had been with for almost seven years, so the theatre was the most cathartic place for me," Scherzinger told British newspaper London Evening Standard.
"It was the only thing that kind of kept me going because I had to keep all that hidden. Every night I just bared my heart and soul on that stage and it was the only thing that really kept me going," added the singer, who is currently dating Bulgarian tennis player Grigor Dimitrov.
