Shake it up, indeed!

Disney starlet Bella Thorne was spotted making quite a splash as she frolicked along a Miami beach this Sunday. Sporting a retro-inspired polka dot bikini, the 14-year-old actress was all smiles as she hit the waves with boyfriend Tristan Klier.

It certainly looks like things are getting serious between these two young lovebirds!

Apart from their Florida vacay together, Bella and her baseball-playing beau have been spotted getting cozy at Coachella and various red carpet events around town. The redheaded cutie even invited Tristan to this year’s White House Easter Egg Roll!
