Hoping she'd join in on the acapella session he called for her attention screaming, "Hey Miley! Miley Miley!" Unfortunately, she wasn't having a bar of his silly antics and quickly sped up as he tried to chase her.
Later that day, Miley, 26, shared a video of the couple on the plane together admitting she wasn't too impressed with his vocals. "I hate it, but for some reason people love it," she said, revealing she's not a fan of his vocal talents. Moments later, Liam recommenced signing the track!

The loved-up couple has been travelling a lot as of late. Liam recently joined Miley in Memphis, Tennessee where she performed her new song, 'Nothing Breaks Like a Heart' at the Beale Street Music Festival. Following their brief stay, they jetted off the New York City where they're preparing to attend the Met Gala.
Ten years after meeting on the set of The Last Song, the duo surprised the world married in December of last year, less than a month after they lost their Malibu home in the California Woolsey wildfires. Miley confirmed they'd tied the knot days later, sharing photos of the couple in formal attire.
