Pop star Britney Spears is set to perform a run of Vegas shows live from the Mojave Desert in a deal worth a reported $30 million (£19 million).

The American singer will unveil her plans at 4am this morning local time during a broadcast for ABC network’s Good Morning America.

Flanked by 1,350 backing dances she will also perform her latest hit single "Work B***h" which was leaked at the weekend ahead of its official release.

Spears plugged the flamboyant event on Twitter, saying: "You definitely aren’t going to want to miss this," adding that "big news" would also be announced.

The dramatic publicity stunt will reportedly cost a huge amount, with transport alone (via helicopter) believed to be in the region of $27,000.

Spears appearances in Sin City are expected to earn her a reported $15 million per year.

The "Hit Me Baby One More Time" singer, 31, is believed to have signed up to perform 48 times annually for two years. Each show will earn her approximately $310,000, according to US website Contact Music.

TMZ claims Spears' contract is for 90-minute shows based at a new theatre in Planet Hollywood.

Artwork for her comeback single, "Work B***h", shows the songstress dressed in a feathery, sparkly showgirl outfit.

Spears follows in the path of other global megastars, such as Elton John, Rod Stewart and Céline Dion, the latter of whom pulled in a figure close to the $100 million mark with a new deal for 210 shows at Caesars Palace last year.

A countdown on Spears’ official website has been stoking fans' interest for the last month, but today’s announcement follows the illegal leakage of her new single at the weekend.

Like Lady Gaga and Katy Perry, Spears is the latest high profile artist forced to rush-release a single after it was released illegally online.

"Work B***h", co-written with The Voice judge will.i.am and Anthony Preston, surfaced on the internet a day early.

On Sunday Spears tweeted her disappointment: "Woke up today and saw that a low quality version of Work B*** had leaked".

More details of Spears' upcoming eighth studio album are expected to be revealed on Good Morning America today, with speculation that it will be called All Eyes On Me.
