Ariel Winter bares her bottom in cheeky bikini video: '2020 looks very promising!'

Ariel Winter has lots to celebrate as she enters the New Year. But according to a video she posted, showing off her bikini body, it seems the 21-year-old may be happiest about recent changes to her physique.

The Modern Family actress took to Instagram on Wednesday to share footage of herself on a warm-weather vacation, looking out into the water before peering over her shoulder and flashing a peace sign. She simply captioned it with the hashtag “#happynewyear” and even tagged her trainer, @mackfit.

Naturally, the comments were flooded with well-wishes for 2020 in addition to comments on Winter’s appearance. “Well, I’m not sure there’s a better way to welcome 2020!” and “2020 looks very promising!” two people wrote. Another commented, “Peaches come to mind for some reason.”

Winters started documenting her fitness journey in October when she posted a video of herself in the gym, working with her trainer Mack on her new goals.

The actress even opened up during an interview with Women’s Health about her decision to switch the antidepressant medication that she was taking, which ultimately helped to balance out her metabolism and allowed her to see more results from her workouts.

“When I changed meds, and started feeling better about myself mentally, losing weight was helpful because it made me feel like I wasn’t just stuck,” she told the magazine. “I hate being stuck anywhere in life.”
