Demi Lovato [1] is officially a self-timer master. At least, that's what we're calling her after she shared a couple of sexy swimsuit photos on Instagram [2]. The 27-year-old "I Love Me" singer [3] posted the pictures on Saturday, showing off a wine red one-piece while relaxing in a hot tub. "Swipe to see how I discovered the self-timer feature for taking pics," she captioned the snaps. She also jokingly called out her photographer, adding, "@angelokritikos - you in trouble boo boo 😝🌴." Many of Demi's followers gushed over the flirty photos, namely her boyfriend, Max Ehrich, [4] who commented with a heart-eye emoji. Now that Demi's discovered the self-timer, let's hope she keeps these steamy posts coming.
