Justin Timberlake Performs At Star-Studded Vegas Resort Opening

Justin Timberlake‘s back in full showman mode … taking to the stage at the theatre inside the lavish Fontainebleau Las Vegas for its grand opening.

The singer was suited and booted Wednesday night in a white tux for his first performance since April 2019 … singing tunes from his catalog of hits during a dazzling night of festivities at the brand-spankin’ new upscale resort.

In the clip, he’s seen performing with a band and backup singer … and later taking to the piano — basically pulling out all the stops for the evening, for which he was paid a hefty $6.1 million … according to The Sun, anyway.

JT’s return to the stage may be an attempt to distance himself from ex Britney Spears‘ sensationalized claims in her memoir “The Woman In Me” … saying she had an abortion while they were together, which she said he pushed for at the time.

She also alleged he’d cheated during their relationship, and put on a “blaccent” for Ginuwine … among lots of other claims.

JT was supported at the event by his wife, Jessica Biel … who looked incredible in a plunging white flowing gown as they arrived arm-in-arm. They later topped off their evening with an appearance at the resort’s LIV nightclub.

The new 150,000-square-foot Sin City resort/casino … owned by Jeff Soffer … which boasts a new era of luxury hospitality, clearly went above and beyond … with even icon Paul Anka taking to the stage and bellying up to a celeb-packed craps table.

Honestly, this is what you call high-rolling — JT, Tom Brady, Cher and Tyga all crowded around to watch the dice. Sylvester Stallone and Kim Kardashian also popped up at the event — and, imagine this … Kim made a low-key entrance!
