In fact, Scherzinger wound up singing basically all of the vocals on the group's 2005 debut, PCD, along with being the only Doll to have a few songwriting credits on the album. As the Pussycat Dolls' record went on to sell millions of copies, Scherzinger collaborated on various songs outside of the group with artists like P. Diddy, Rihanna, Avant, Will Smith, and Belinda. As the Pussycat Dolls continued to support their debut on the road, Scherzinger readied the release of her first solo album, Her Name Is Nicole..., scheduled for release in late summer 2007. The album is slated to feature various guest spots, including ones from Akon, Timbaland, and will.i.am. Scherzinger also plans on returning to her first love of acting at some point; her résumé already includes bit parts on the television shows My Wife and Kids and Las Vegas, as well as in movies Love Don't Cost a Thing and Chasing Papi.

Her first solo single, Whatever U Like featuring rapper T.I., was released in July 2007. The song was unsuccessful commercially and with critics, and it was soon announced that Baby Love would replace "Whatever U Like" as the "lead single" from the album. Media reports commented on the fact that both Interscope's and Scherzinger's official websites started in September 2007 to refer to "Baby Love" as her first single. After both these singles were unsuccessful in North America ("Baby Love" charted well in Europe and Brazil however), a poll was placed on Scherzinger's website, asking fans to vote for the third single. Choices included: "Supervillain", "Happily Never After", "Who's Gonna Love You", and "Power's Out". On November 28 the poll was updated and the songs "Power's Out" and "Supervillain" were removed and replaced with "Puakenikeni" and "Physical". It was announced via the website on December 10 that "Puakenikeni" was to be the next official single to be taken from the album, subsequently "Supervillain" and "Puakenikeni" were both released as iTunes downloads only. As with Scherzinger's earlier solo singles, they failed to make any impact on the U.S. charts. Following this, Interscope announced that Scherzinger's album would be put on hold, and she said she would continue to record new tracks.

In April 2008, Scherzinger recorded a cover version of "Rio" by Duran Duran for an advertising campaign for Unilever's Caress brand of body wash. A commercial video was released, and the single was released via download only, after May 2008. In 2008, in support of Barack Obama, she was one of many musicians to contribute to a track by will.i.am called "Yes We Can". Also on September 5, 2008, Scherzinger joined an all-star cast to perform the charity song "Just Stand Up" on live TV. This is currently Scherzinger's last performance as a solo artist before embarking on the Pussycat Dolls new World Tour.

Speaking about the delayed release of her solo album, in September 2008 Scherzinger said "Despite what other people might write, it was my decision, ultimately. I actually put some of my solo songs on the Pussycat Dolls' new album Doll Domination. Everything is all about timing. I believe it will come out next year, and it will be able to coexist wonderfully with the Dolls' album. It's completely separate from what you've heard with "Baby Love" and "Whatever U Like," and I'm still working on it — that's what happens when you're a perfectionist."

In October 2008, she was invited to promote Clear Shampoo and Conditioner through a commercial, succeeding Rain who also endorsed Clear Shampoo and Conditioner. Both commercials were reportedly aired throughout Southeast Asia. In 2008, she also had done a commercial with Lebron James in a sneaker commercial. She had also made a "Bench Body" commercial which was promoting underwear for "Bench Body".

Scherzinger's new single, "Poison", premiered on her official website and YouTube account on October 14, 2010. It is due for release on November 29, 2010. A picture from the video shoot was revealed by MTV, showing Scherzinger dressed provocatively. "Poison" serves as the first single from the album and peaked at number three on the UK Singles Chart becoming Scherzinger's most successful single.
