Lance Bass: Being a Father Has 'Completely Changed' Justin Timberlake

Bass reunited with Timberlake for the first time since he became a dad

A lot has changed since Justin Timberlake and Lance Bass became household names in their ‘NSYNC era.

Bass — now officially a member of The Meredith Vieira Show — bumped into Timberlake at the NBC studios on Wednesday while the latter was there to appear on The Tonight Show.

Bass, 36, later told Vieira it was the first time he’d seen Timberlake, 34, since JT’s son with Jessica Biel, Silas Randall, was born in April.

“It’s been five months, and it’s so amazing to see a friend go through this, because, you know, I grew up with him since he was 14 years old,” Bass said. “But to see this amazing dad now and all he wants to talk about is the kid.”

Timberlake has “completely changed,” Bass continued, adding, “You have to. I mean, I can’t wait to be a dad myself just because I would love to know what the selflessness feels like.”

Timberlake had some praise for fatherhood himself, telling Jimmy Fallon, “It is the most insanely amazing, most beautiful, unbelievable thing that can ever happen to you.”

The “Tunnel Vision” singer has been busy doting on his new mini me — just look at the adorable photos he shared this week and that cute Father’s Day Instagram — but fatherhood isn’t stopping Timberlake’s signature antics with his buddy Fallon. On Wednesday, the guys proved they can still dance like Beyoncé when they busted out their “Single Ladies” moves at the U.S. Open.
