Former Pussycat Doll Nicole Scherzinger has carved another notch in her musical career by releasing her second solo album, titled Big Fat Lie. Scherzinger has reportedly admitted that the album tackles her heartbreak over her boyfriend, Formula One driver Lewis Hamilton. The couple apparently spent a long period apart in 2013 and reunited earlier this year.

Scherzinger celebrated the release of Big Fat Lie by holding a signing for her new LP at HMV in London on Monday, October 20. She showed up in an eye-popping ensemble of a black bralet covered by a white jacket and white skirt. Her lips were a bright red to match her red studded booties, and her look was made edgy with giant metal accessories and some of her hair pulled back into small braids. Scherzinger reportedly looked happy and goofed off in front of cameras, delighting the fans who came to see her.

According to London Evening Standard, Big Fat Lie was also an opportunity for Scherzinger to address some old personal issues such as past relationships and her eating disorder. “It’s a very personal album to me. It’s a transitional album, and it’s very honest and authentic,” Scherzinger said. “I’m in a different place in my life now. I feel a bit more confident and comfortable in my own skin to be able to talk about things that I hadn’t talked about before.”

Writing the album was apparently like going through “therapy” for Scherzinger, who also said, “It feels good to be truthful because not everyone’s perfect.”

Before she launched her album, Scherzinger was also seen partying in a little black dress at the Toy Room Club with friends on Saturday night, only stopping at 4 AM the next day. Scherzinger had also put some time in for a good cause at the Stand Up To Cancer 2014 telethon on Friday, October 17, where she performed a single from Big Fat Lie.

Big Fat Lie will be available in the US early next year via Epic Records.
