Ariel Winter has become more confident with her curves. Just recently, the actress showed off her bum in a new photo taken while she was vacationing in Bora Bora.

In the pic posted on her Instagram account, the 18-year-old actress can be seen wearing a white two-piece swimsuit. She is joined by her friend, Jessie Berg, in the snap. The two are on board a boat and are basking under the sun.

Just a day ago, Winter also shared a photo of herself wearing a more conservative one-piece swimsuit. According to the Daily Mail, Winter was also joined by her “Modern Family” co-star Nolan Gould, as well as their two other guy friends, on the trip.

Winter plays the role of Alex Dunphy in the hit ABC TV sitcom. She has been part of the show since its premiere on Sept. 23, 2009. Alex is the smartest child of Claire (Julie Bowen) and Phil (Ty Burrell). She has an older sister named Haley (Sarah Hyland) and a younger brother named Luke (Gould). Just recently, Alex went off to college so she had to be away from her family. However, she reunites with them whenever there are special occasions.

In the upcoming episode of “Modern Family” Season 8, titled “Sarge & Pea,” Alex will get a visit from her Uncle Cam (Eric Stonestreet) at the coffee shop she is working at. While there, Cam and Haley will cross paths with an anonymous parent who caused a commotion during Lily's (Aubrey Anderson-Emmons) school recital. Cam will confront the parent, making a scene that could possibly cause Alex to lose her job.

“Modern Family” Season 8, episode 11 will air on ABC on Jan. 11 at 8:30 p.m. EST.
