Cole Sprouse Shares Topless Photo of His "Little Muse" Lili Reinhart on Her Birthday

Lili Reinhart is 22 years old! To celebrate the big day, her Riverdale costar turned real-life boyfriend, Cole Sprouse, shared an intimate topless photo of her looking like the gorgeous, angelic human she is. Cole paired the racy snap with a sweet caption, writing, "Both the birthday and the gift. My little muse, happy birthday my love." Ugh, *swoons.*

Last month, Lili shared an equally adorable Instagram message to honor Cole's 26th birthday. "It seems as if the world would still be a stranger to me, if not for you," she wrote alongside a cute photo of her beau from their recent trip to Mexico. "I'm so thankful that our paths intertwined to form this beautiful adventure. Happy birthday, my love." Yep, it looks like these cuties both call each other "my love," and yep, the Bughead-obsessed fangirl in me is LOSING IT.

Read on to see more gorgeous photos of Lili that Cole has snapped and shared since the two lovebirds began dating.
