Alongside Lili Reinhart, Cyrus' boyfriend was one of her guests on her Instagram Live show, Bright Minded, on Thursday. During his appearance on the show, Simpson read the "Wrecking Ball" singer a poem he had written about her, with her smiling from ear to ear.
"Babe! I'm freaked! I'm the most beautiful?" she asked when he concluded his piece, which is featured in his poetry book, Prince Neptune, out next week.
"You're the most beautiful, babe," Simpson replied.
Before he "left" Cyrus' Instagram Live, the Australian singer showed off his new buzzcut, courtesy of Cyrus. "I love it. You look so cute!" she raved, before saying goodbye to her beau.
"He's the only one that's hung up on me first. That's why I'm into this guy," she quipped when he signed off. "That's what I need."
