"Modern Family" star Ariel Winter proudly showed off her new curves on social media on Monday, after undergoing breast reduction surgery.

The 17-year-old actress and her boyfriend of two years Laurent Claude Gaudette recently attended a family wedding, according to People.

Winter and her beau both dressed in their finest for the event, with her donning a white bodycon dress paired with a red lip and him in a debonair suit. A photo, uploaded by the actress to Instagram, presents the couple in their elegant attire.

"My Czech shmooey spending a weekend with us Greeks for the wedding," Winter captioned the photo. Winter shared another wedding photo earlier in the evening of her cousin's first dance.

"The most beautiful bride and groom!!!" she wrote. "I feel so lucky to have been a part of this day filled with love and beauty."

The actress, who has played the role of daughter Alex Dunphy since the inception of the ABC show, has not been modest about showing off her shapely figure. She's been seen wearing formfitting gowns since August, after having breast reduction surgery in June. The actress reduced her breasts from a size 32F cup to a 34D.

Winter spoke about how others say she's inspired them to consider breast reduction surgery for themselves. After suffering back pain, the actress says relief was well worth the procedure.

"Girls are tweeting me and saying like, 'Oh, this wouldn't be accepted where I am, but now that you did it and opened a conversation about it, I can actually like talk to my friends and family about the possibility of this,'" Winter told People on Friday at Teen Vogue's Young Hollywood party.

While she is most known for her role on "Modern Family," Winter is also the voice of the main character in the Disney Junior show "Sofia the First."
