Some things are better left just unheard. Such is the case with Britney Spears' real singing voice, making its wave around the Internet as allegedly her 2001 Las Vegas concert vocal track amidst rumours circulating that she will be lip synching the 31-year old's "Britney: Piece of Me" shows in Las Vegas. Britney was repeatedly accused of prerecording tracks and lip synching in the past and to say that her vocals are off-key would be an understatement.

Britney Spears has also been videotaped many times exchanging her Louisiana accent for a British twang. Facebook and Twitter fans called it "iriitating" and "weird" while one said,"Britney used to be awesome, but now she talks fake." She repeatedly referred herself to "Britney Bitch" made famous in her 2007 hit, "Gimme More."

"When Britney uses the British accent or appears to take on another identity, does she know she's Britney Spears?" LA psychologist Renee Cohen talks about opinion on Spears. "When someone has dissociative identity disorder, formerly called multiple personality disorder, each identity is split off from the other. Each identity has its own memories, name, emotional characteristics and behavioral traits."

Aside from Britney's off-key notes and quirks, fans no doubt appreciate her sexy, body-conscious costumes and dance moves, including a revealing and daring fluffy bustier. Her accent and identity issues may be terrible but her figure is undeniably looking good. She now talks in full sentences, which is a big improvement from her X Factor judging stint. Overall, Britney looks to be in a much healthier place now and her upcoming tour might just prove to be just as arresting as concerts from her 19-year-old past.

Britney's eighth studio album called 'Britney Jean' will be released on Dec. 3, 2013. She will perform a $30million residency show with Planet Hollywood Resort and Casino in Las Vegas starting on Dec. 27, 2013 with a total of 100 shows in 2014 and 2015. The two-year tour will mix new and old hits with a theater meets club feel.

Britney's father Jamie Spears receives $16,000 a month as her conservator and $1,200 for office expenses. In his filed court documents claiming for more money, he says "my rent has steadily escalated over the last three years. I request that I be reimbursed an additional $800.00 per month for my office expense from November 2012 to August 2013." He also requests his future office expense budget to be increased to $2,000. Jamie was an important part in securing deals with Planet Hollywood and X Factor.
