Justin Timberlake is supported by wife Jessica Biel at his album release party in West Hollywood

Justin Timberlake was supported by his wife Jessica Biel at his album release party one night after reuniting on stage with his boy band NSYNC.

The 43-year-old musician was spotted outside the event with his 42-year-old actress wife on Thursday evening, which was held at Dan Tana’s in West Hollywood.

Justin threw a soiree at his favorite Italian restaurant to celebrate the release of his sixth solo studio album titled Everything I Thought I Was.

Other celebrity guests included his NSYNC bandmate Lance Bass, 44, fresh from their performance together.

The night before, NSYNC reunited on stage at Justin’s concert in Los Angeles for their first performance together in over a decade.

At the One Night Only show celebrating his upcoming album release, the 43-year-old singer put on a performance and was joined by his bandmates at The Wiltern for a surprise reunion.

At the end of his concert, he brought out Lance alongside JC Chasez, 47, Joey Fatone, 47, and Chris Kirkpatrick, 52, for a medley of their hits and their new song, Paradise — which will appear on Timberlake’s new dossier.

His upcoming album, Everything I Thought It Was, will be available Friday and he will then leave to perform in his native Memphis and then New York City.

Joining the crowd were John Legend and Chrissy Teigen, who shared a reaction video of themselves going wild over the surprise — as well as Travis Kelce sans Taylor Swift.

After performing his biggest hits, some of his new music and bringing out Coco Jones for their remix of her song ICU, the introduction of NSYNC’s Gone began to the surprise of his fans.

The curtain was pulled as Chasez, Fatone, Bass and Kirkpatrick joined their bandmate to take the stage as a quintet for the first time since 2013.

While the DJ was creating a version of Girlfriend, the fivesome interacted with their excited and shocked fans in the audience.

They then performed a short but exciting performance of their hits It’s Gonna Be Me and Bye Bye Bye from their 2000 album No Strings Attached.

Timberlake and his bandmates also sang their new song Paradise for the first time.

NSYNC last performed together at the 2013 MTV Video Music Awards, when Timberlake received the Video Vanguard Award.

Since their last album in 2001, titled Celebrity, Timberlake has focused largely on his solo career.

The group reunited without him during Ariana Grande’s headlining performance at the 2019 Coachella Valley Music and Arts Festival.
