Cole Sprouse and Lili Reinhart are taking their onscreen romance off screen. The Riverdale costars, who play fan-favorite couple Betty and Jughead on The CW series, were spotted taking a romantic stroll by the beach in Hawaii earlier this week. Lili looked amazing in a striped two-piece bikini, while Cole went shirtless in a pair of red swim shorts. While the two have kept mum about the state of their relationship, they didn't have a problem showing sweet PDA as Cole wrapped his arm around Lili and she held onto his hand. See the rest of their adorable outing ahead.
