Jessica Biel is a big fan of husband Justin Timberlake’s hot new single “Selfish.”

On Saturday, Biel, 41, posted a TikTok of herself listening to the song nonstop as she went about her day.

“POV: Trying to get anything done the past 24 hours,” she wrote over the video, which featured clips of her brushing her teeth, doing some casual yoga in the bathroom and lip-syncing to the camera as her husband’s track played.

 Biel captioned the video, which has so far been viewed more than 2 million times.

Timberlake, 42, dropped “Selfish” on Friday, and the single marked his first release in six years, following up 2018’s Man of the Woods. The track is the first off his forthcoming album, Everything I Thought It Was, which is scheduled to drop March 15.

On Saturday, he performed the song on Saturday Night Live, where he was the night’s musical guest, alongside host Dakota Johnson, making his return to the famed late-night sketch comedy show after more than a decade.

He also performed a new song, “Sanctified,” featuring rapper Tobe Nwigwe, which also will be included on the forthcoming album.

The SNL performances came days after he told Apple Music 1’s Zane Lowe that he “ended up with 100 songs” for the album, so “narrowing them down to 18 was a thing.”

He also shared how “excited” he is about the record, which he “worked for a long time on.”

“I think every artist probably says this, but it is my best work,” Timberlake said, adding that it has “moments that are incredibly honest, but also, there’s a lot of f—ing fun on this album.”

“I was able, on some of the songs, to look back at the past and have a real, not a refracted perspective of what it was because they always say … you always hear that thing about, well, there’s never any truth, there’s just everybody’s perspective of what happened,” he continued. “But to really look at it and be able to metabolize and verbalize my perspective on it, I don’t think I’ve ever really done that before.”

As for the title, the “Mirrors” singer said it was inspired by how “some of the songs are more introspective and some of them are more what I think people know me for.”

The Grammy-winning singer and Biel, who have been married since 2012, are very private about their relationship — and their kids.

The couple shares sons Silas, 8 ½ , and Phineas, 3 ½ , and Timberlake recently told Jimmy Fallon of his children, “They’re both so cute.”

“You lucked out,” Fallon agreed. “Yeah, you got a good kid.”

“They run our house, it’s crazy,” Timberlake admitted. “It’s crazy.”
