Justin Timberlake & Anderson Paak's 'Don't Slack' Watch

But it all works out in the end.

Justin Timberlake and Anna Kendrick are pals on an epic musical adventure in the upcoming Trolls World Tour animated sequel, but in the just-released video for JT and Anderson .Paak's contribution to the soundtrack, "Don't Slack," he's kind of freaking her out.

The playful clip, directed by Calmatic, finds Kendrick just trying to relax at home in her jammies while Timberlake and .Paak keep popping up to scare her.

First .Paak serenades her from inside the shower and the fridge, while Timberlake dances down the hallways like a whirling dervish and steals her newspaper to carve a love note with scissors just before the dynamic duo jump on her bed while she's trying to nap. It's all pretty annoying, until they set up a mini-concert in her living room -- complete with a "You're Doing a Great Job" banner -- which gets her dancing along to the song's irresistible rhythm.
