Watch Miley Cyrus and Liam Hemsworth Sing Along to Justin Bieber's 'Love Yourself'

This Miley Cyrus and Liam Hemsworth video totally brings back memories of that cute singing in the car scene from their 2010 movie The Last Song.

Cyrus, 23, shared a video on Instagram Monday of her joy ride with Hemsworth, 26, in which the couple karaoke to Justin Bieber's hit "Love Yourself."

In the clip, the pair sing aloud the lyrics with The Voice star's melodious tone while the Independence Day Resurgence actor tried his best to harmonize. Also starring in the short music video was Cyrus' new dog Barbie.

"Babe stop, seriously," the pop star said to her former fiancé.

Cyrus and Hemsworth dated for years before they got engaged in May 2012. Though they split in September 2013, the pair recently reconnected and have been spotted on several outings together. In January, the singer began rocking her 3.5 carat engagement ring again.

Neither have publicly confirmed the status of their relationship, but Hemsworth told GQ Australia that "people will figure it out, they already have... They're not dumb."
