The show, which opened on December 27, 2013, was initially set for two years; it was well received by critics and also achieved huge commercial success.

[2] After completing the Femme Fatale Tour in December 2011, rumors circulated of Spears performing at a concert residency in Las Vegas.

[6] Spears's manager, Larry Rudolph, stated the show was not comparable to previous or current Las Vegas stints.

[7] On September 25, 2014, Spears confirmed on Good Morning Britain that she had extended her contract with The AXIS and Planet Hollywood to continue the show for two additional years.

The venue closed in late October 2012 to undergo a $20 million renovation with lighting, sound and stage to accommodate the show.

[17] The show begins with a video of a young Spears dancing throughout her childhood home in Louisiana, dreaming of being a performer one day.

Notable participants in this segment have been Nicole Richie, AJ McLean, Mario Lopez, Kathy Griffin, Tyson Beckford, Perez Hilton, Lance Bass, Dolph Ziggler, and Adore Delano.

[19] According to Danielle Genet of ABC News, the opening show "drew rave reviews [...] for Spears' lavish, entertaining spectacle.

Schillaci also commented that long-time fans would appreciate the concert as it is "more of a look backwards than forwards," and added that, while Spears may not sing completely live, "[the singer's] sweet voice shone through the backing, or we could hear her catching her breath between numbers."

She concluded her review saying that "if you're looking for a powerhouse vocal performance in your Vegas entertainment, head over to The Colosseum for Celine Dion.

"[21] Marco della Cava of USA Today praised the concert, saying that Spears's mission "to turn a cavernous 7,000-seat amphitheater into a raging nightclub" was accomplished.

[19] Mikael Wood of the Los Angeles Times commented on Spears's singing, writing that "the singer appeared to be lip-syncing for the majority of her performance"; however, he added that the production "has plenty to distract you from the vocal question.

"[23] Wood also thought that, while "'Piece of Me' hits most of the high points in Spears' songbook," songs like "Boys", "3", and "Do Somethin'" could "have been replaced with superior cuts from her recent albums.

"[23] Writing for Billboard, Keith Caulfield noted that "vast majority of the show was lip-synced, and only occasionally were any seemingly live vocals heard."

[24] Rachel Maresca of New York Daily News noted that Spears "wowed the crowd" on the opening night, and added that the singer "pulled out all the stops to entertain her fans with plenty of theatrics on stage.

"[25] Laura Hertzfeld of Entertainment Weekly revealed that "[she'd] have loved to have seen more" of the concert as "it was the most connected to [Spears] as an artist that one can feel from the audience.

"[26] Las Vegas Sun journalist Robin Leach said that Spears "proved that she's still reigning royalty in the music world" with the residency, adding that the show is "an amazing and incredible accomplishment because in less than two hours, Britney changed the look of our Strip entertainment scene.

For the first time, she single-handedly brought the spectacle of a touring arena show into a nightclub-like theater and pulled off the gamble with a flawless performance."

"[27] Caryn Ganz of Rolling Stone wrote a mixed review, saying that, "viewed through a lens of diminished expectations [...]), Britney: Piece of Me is an entertaining tour through the 32-year-old star's nearly 15-year recording career.

Compared to pop spectacles staged by Madonna and Beyoncé [...], however, the weaknesses that remain in Spears' live act are stark."

The reviewer wrote, however, that "the show featured flashes of greatness," with the performances of "Work Bitch", "...Baby One More Time", "(You Drive Me) Crazy", "Circus" and "Everytime" being the stand outs.

[28] In 2015, the revamped show received a cautious endorsement by Julie Bone of The Washington Post: "If you're even vaguely interested in pop music, dance and the art of performance, see 'Piece of Me.'"

[32] It was also reported that the residency brought an additional $20 million in annual earnings for Planet Hollywood, allowing it to revitalize the property in terms of both finances and popularity.

[35][36] On November 5, 2014, a special ceremony was held in honor of Spears at The Linq Promenade, where she was presented with a Key to the City of Las Vegas by Clark County Commissioner Steve Sisolak and Planet Hollywood regional president David Hoenemeyer.

[35] Since the show's debut, other major performers, such as Jennifer Lopez, Pitbull, the Backstreet Boys, Mariah Carey and Lady Gaga, have followed in Spears's footsteps and accepted residency offers as well.

Rascal Flatts manager Clarence Spalding says Spears' residency helped inspire his act's mini-residency at Hard Rock Hotel & Casino's Joint venue this spring.

[39] After completing the original run of the show, Spears revealed that the extension would feature updates to the set list, choreography and costumes.

[42] On April 7, 2017, Spears's manager Larry Rudolph announced that the Britney: Piece of Me residency at The Axis Theatre at Planet Hollywood Resort & Casino in Las Vegas would end on December 31, 2017, with the expiration of her contract with Caesars Entertainment.

[48] On May 17, 2015, Spears performed her single "Pretty Girls" with Iggy Azalea for the 2015 Billboard Music Awards from her residency stage.

[50][51] On December 21, 2017, Spears announced on her social media platforms that she would be broadcasting a special performance from The AXIS Theatre at Planet Hollywood on Dick Clark's New Year's Rockin' Eve '18 with Ryan Seacrest.
