Justin Timberlake is heading back to late night! The “Mirrors” singer is set to join The Tonight Show Starring Jimmy Fallon on Thursday (Jan. 25) as a guest alongside Molly Ringwald and musical guest Flo Milli.

Because Timberlake and Fallon are longtime friends, fans are speculating that Timberlake will use the late night appearance to announce a new album era. He’s been teasing fans via social media over the past week, wiping his Instagram clean before posting a series of photos from what looks like a music video set.

“EITIW,” he captioned the post, with fans theorizing that the single will be called “Everything I Thought It Was.” Redditors even tracked down a trademark application filed by a mysterious LLC early last year for that phrase, as well as for “Everything I Thought It Was…A Sonic Film.”

Should Timberlake release a new album, it would mark his sixth album and first since 2018’s Man of the Woods. That project marked his fourth consecutive No. 1 on the Billboard 200, where it charted for a total of 19 weeks. Just days after the album’s Feb. 2 release, he performed at the Super Bowl LII halftime show in Minneapolis. In September, Timberlake reunited with *NSYNC to release “Better Place” for the Trolls Band Together soundtrack, marking the group’s first musical release since 2002 (when the Neptunes remix of “Girlfriend,” featuring Nelly, arrived).
