Joey Fatone brought his daughter Briahna Joely to Justin Timberlake's exclusive performance on behalf of Citi/AAdvantage & MasterCard Priceless Access on Thursday night at the Hammerstein Ballroom in New York City.
He took to Twitter to share a sweet snapshot from the fun reunion.
"Cool how time does not go by .. But it does when my kid stands next to a brother and she is almost as tall as him lol," he wrote along with the cute candid.

Timberlake performed a number of hits, including "Cry Me a River" and "Señorita," from his debut album "Justified," plus newer jams, like "Mirrors" and "Not a Bad Thing," from his most recent albums, "The 20/20 Experience – Parts 1 and 2."
Other famous concertgoers besides Fatone included "Orange Is the New Black" star Laverne Cox, Candice Accola, Jessica Szohr and Meredith Vieira.
Gotta love a mini *NSYNC reunion!
