Lady Gaga is closing out her epic 2018 with the launch of one of her most ambitious endeavors yet, and she's making an eye-popping return to the vibrant aesthetics of her past for her Las Vegas debut.

The triple-threat has officially taken Sin City by storm, as Gaga opened Enigma, her residency at the Park MGM Las Vegas, on Friday night (Dec. 28). Though her stellar performance in A Star Is Born has dominated the bulk of Gaga's 2018, Enigma brings Gaga back to the stage and with futuristic, mind-blowing props, set pieces and costumes worthy of the occasion.

After she shared a brief teaser for the show before the performance, Gaga posted a backstage pic of one of her many Enigma looks that featured a strong brow, vivid tangerine lips and cerulean hair -- a vibe that throws to the pop art-channeling style she sported for her "Telephone" visual for her collaboration with Beyoncé in 2010.
