Britney Spears' Vegas show ticket sales set to go through the roof

Despite conflicting reports about ticket sales for Britney Spears' Vegas concerts, it has been revealed that the popstar is about to own the Sin City.

The singer will be performing 48 shows a year for the next 2 years, according to the contract obtained by TMZ.com.

Tickets are available now for the first 16 shows.

For the first 16 shows, a total of 73,600 tickets were up for sale. The number of tickets actually sold is impressive -- 70,242.

Of the available, remaining, 3,358 tickets, 2,887 are in the nosebleed section.

Sources have said that they're actually talking about adding shows, and if that happens Spears will rake in even more than the 15 million dollars a year she's already guaranteed.
