Britney Spears' Vegas Costumes

The Princess of Pop pulled in some major moolah during her time in Sin City.

The numbers are in and they're anything but "Toxic."

According to Billboard, Britney Spears' "Piece of Me" show in Las Vegas had an overall gross of $137.7 million, based on ticket sales alone. The four-year residency at Planet Hollywood's Axis Theater sold 916,184 seats total for its 248 shows, which ran from December 2013 to New Year's Eve 2018.

It's worth noting these numbers are just for ticket sales and don't include the additional cash flow generated through merchandising and alcohol sales at the show.

When Britney first signed her deal with Caesars Entertainment, she reportedly pulled in $310K a show for two years, but -- according to TMZ -- that pay day was bumped to $475,000 after ticket sales got off to a booming start.

Now that the residency is over, Spears will take her show on the road in 2018. She announced a limited, 23-date tour earlier this week that will take "Piece of Me" to the East Coast, as well as Europe. It'll kick off July 12, 2018 in Washington, DC and end August 24, 2018 at London's O2 Arena.

There are also reports she'll return to Las Vegas at the end of the year, but she has yet to confirm or comment.
