Nicole Scherzinger is dripping in fake blood while signing autographs for fans at her Broadway debut of Sunset Boulevard during opening night

Nicole Scherzinger signed autographs while covered in fake blood after making her Broadway debut in the much-anticipated revival of Sunset Boulevard on Sunday.

The former Pussycat Doll singer, 46, seemed in good spirits as she greeted fans outside St. James Theatre while still dressed as her character Norma Desmond.

Nicole, who was still dripping with fake blood and wearing her long black dress, signed fans programmes as they waited outside the stage door.

She took to the stage in New York City as leading role of faded actress Norma Desmond in the classic Andrew Lloyd Webber musical, after previously playing the character on London's West End.

In another snap, the Masked Singer judge looked thrilled as she celebrated her debut with a glass of champagne.

The actress received five standing ovations for her incredible performance throughout the opening night of Sunset Blvd.

Ahead of the show, Nicole took to Instagram to share a snap of herself with Andrew Lloyd Webber and Jamie Lloyd as they rehearsed ahead of opening night.

She penned: 'Tonight I make my Broadway Debut. I can hardly believe it. Little Nicole has waited for this her whole life. And I get to do it with this beautiful cast and these two heroes of mine

Nicole initially played the role of Norma when it opened in London last year, whilst West End legend Rachel Tucker served as her alternate.

She and co-star Tom Francis both won an Olivier for their efforts , and Tom has joined the Don't Cha singer on Broadway.

Nicole and Tom are also joined in the show by fellow London co-stars Grace Hodgett-Young and David Thaxton as they all made their Broadway debuts.

Nicole recently admitted that despite her success in theatre, she had initially felt 'discarded' by the industry following her pop career.

She told People : 'I'm [46] years old. I've never been more strong — physically, mentally, emotionally. I'm in my prime. There is no better time for me to create work that is meaningful in this world.

'That's the tragedy: is that you're in the best place in your life. You're so full, you have so much to give, and people have discarded you, and dismissed you and said 'Your time's up...''

Nicole then insisted that it has been her 'lifelong dream' to make it to The Great White Way, which comes after appearances in shows like Cats and Rent since her pop heyday.

Nicole's success in the London run of Sunset Boulevard did not go totally without a hitch as she had a stumble on her way up to the stage during the awards ceremony.

After kissing her fiancé Thom Evans , Nicole carefully made her way to the Royal Albert Hall stage in her daring gown .

Host Hannah Waddingham helped her up the steps but as she reached the top, the actress stumbled, with actor David Oyelowo reaching out to help her.

In her acceptance speech, she said: 'First of all I would like to thank god for saving me from that trip right there. But seriously, without him I am nothing.'

Ahead of the opening night on Broadway, Nicole put on a leggy display in a short white dress as she celebrated her starring role at a cocktail party in New York on Friday.

Nicole looked sensational in the crisp number that featured puffy sleeves and showed off her toned legs.

She opted for a slick of striking red lipstick and heavy eyeshadow and pulled her dark locks into a ponytail,
