Ariel Winter bares her bottom with Luke Benward at Santa Barbara.

Ariel Winter looked absolutely sensational in a blue and white tie-dye bikini as she enjoyed a fun-filled afternoon on the beach in Santa Barbara.

The 23-year-old Modern Family star was the picture of relaxation as she walked barefoot with her hunky boyfriend, Luke Benward.

In addition to blissfully chatting away, the bombshell could be seen affectionately wrapping her arms around the Dumplin' actor.

Her platinum blonde tresses were perfectly straightened as they cascaded past her shoulders and she soaked up the sunshine.

For their fun excursion on Friday, Benward was dressed in a colorful cap and shirt, but later stripped down to just a pair of black board shorts.

Meanwhile, Winter kept her loose floral kimono on as she walked on the warm sand after she was seen reading a copy of Abigail Dean's best-selling book Girl A on a beach chair.

When the duo first arrived to the beach, Winter rocked a tiny white romper and kept her mouth and nose covered with a hot pink face mask amid the ongoing COVID-19 pandemic.

Additionally, the duo both protected their eyes against the sun's UV rays by wearing sunglasses.

Showing off the playful side of their relationship, the duo attempted to skip rocks and could be seen tossing stones into the ocean's breaking waves.

After a few unsuccessful attempts, Winter bent over and found more rocks, which she handed to Benward.

While stone-skipping is possible at the beach, it's easier when the water is flat and calm. Since December 2019, they've been dating and began living together in her $3.5million farmhouse-style residence in Studio City, complete with five bedrooms, six bathrooms and a pool house late last year.

The Phineas and Ferb star and her man previously resided in her similar nearby five-bedroom, five-and-a-half-bathroom for $2.8million, three years after she bought it for just under $2.7million.

Their romanic union began a few months after Winter and ex-friend Levi Meaden split after almost three years of dating. Winter rose to fame as Alex Dunphy on ABC hit sitcom Modern Family.

The show ended last year after 11 seasons and aired its final episode on April 8, 2020.

She and Benward recently wrapped production on their upcoming movie Don't Log Off, which is set in the early days of the coronavirus lockdown.

Their project, her first since Modern Family wrapped, is the comedy-thriller is about a group of friends planning a virtual surprise party, as the birthday girl goes missing.

The lovebirds have gotten much more serious since isolating together amid the COVID-19 pandemic with their five dogs.

Earlier this month, they rang in their second Valentine's Day together, which she documented on her Instagram account.

She posted some cute snaps of her live-in beau, 25, showering her with red roses as well as one of him holding a large heart-shaped balloon with 'I love you' written on it.
