"There were a lot of moments when I was with them that I was distant and stand-offish," she said. "I never opened up to them to talk about my problems and I would shut myself away – and push them away – because I was battling this horrible secret illness, bulimia."Scherzinger says that "it was all wrapped up with my low self-esteem and a crippling lack of confidence." It's taken awhile for the singer to deal with these issues, but it appears that's she's in a much better place in her life. Nicole's road to solo stardom has been a long and tough one. Despite having all the makings of a superstar, none of her solo material has, erm, stuck the way things did with PCD. With an apology out in the air, it only encourages our wish to see Nicole reunite with PCD. Aside from Fifth Harmony, the industry could really use a girl group who knows how to whip out some killer dance tracks and intense choreo. Only time will tell, but for old times sakes, who could forget this OMG moment when the band opened up for B's Circus tour?
