Timberlake returns to voice Branch in this third Trolls movie opposite Kendrick as Poppy. This time, Branch and Poppy are a couple, and she finds out Branch used to be part of a boy band called BroZone with his four estranged brothers (voiced by Troye Sivan, André, Daveed Diggs and Kid Cudi).

Amy Schumer and Andrew Rannells play pop-star villains who kidnap one of his brothers, kicking off a new adventure.

Wednesday's red carpet event is one of the few public appearances made by Timberlake since the release of his ex Britney Spears’s memoir The Woman in Me, in which she writes of their relationship that lasted from 1999 to 2002. 

He was spotted for the first time days after the book’s release last month in photos shared by the Daily Mail that showed him and his family, including Biel, as they arrived in Cabo San Lucas, Mexico, for a vacation. 

Timberlake was photographed the following week at a PGA Tour event at the Diamante resort’s El Cardonal Golf Course in Cabo. He took part in a celebrity four-hole scramble for the PGA Tour’s World Wide Technology Championship. 

The singer also stepped out at a charity event for Pharrell Williams' Joopiter clothing auction with Kenzo artistic director Nigo.

As Timberlake appeared in headlines stemming from revelations made in Spears's book, a source told PEOPLE in October that he was focused on his family and work, including the *NSYNC reunion and Trolls movie.

"He’s happy at home with Jess and their kids and he’s focusing on new music. He’s in such a great place," the source said.

Trolls Band Together is in theaters now.
