Britney Spears is saying goodbye to a chapter in her life.
The 35-year-old superstar announced the final 18 show dates of her Las Vegas residency at The AXIS at Planet Hollywood Resort & Casino on Monday, which will run from Sept. 3 through Dec. 31.
"As I prepare to say goodbye to Piece of Me, I had no idea how magical this experience would be," Spears said in a statement. "Having my fans from around the world come see my show has been amazing. I love Las Vegas and will miss performing this show."
The final dates are September 3; October 11, 13, 14, 18, 20, 21, 25, 27, 28; November 1, 3, 4; and December 19, 27, 28, 30, 31. Tickets will go on sale to the public Friday, April 14, at 10 a.m. PT.
Over 700,000 fans have experienced Britney: Piece of Me since it opened in The AXIS -- which was designed exclusively for Spears' show -- on Dec. 27, 2013. As of January 2017, the show has grossed over $100 million in ticket sales.
On Monday, Caesars Entertainment senior vice president of marketing and entertainment, Jason Gastwirth, left the door open for Spears to return.
"When we first announced Britney: Piece of Me four years ago, we were certain that Britney's residency would revolutionize the entertainment landscape in Las Vegas, and are thrilled at how successful the show has been," Gastwirth said in a statement. "Caesars Entertainment has always led the evolution of Las Vegas entertainment. Britney's emergence in this market paved the way for other artists to make Las Vegas their home and as a result, the top entertainment destination in the world. We look forward to working together with Britney again in the future."
A source close to the pop star confirmed to ET on Saturday that she was ending her residency at the end of the year, as her contract with Caesars Entertainment expires. "We will see what the future holds next for her in Vegas, and other projects," the source said.
