Sarah Hyland and Modern Family Sibling Ariel Winter Bond on Wedding Day: 'Sisters For-Eves'

The Modern Family cast is as tight as ever.

During Sarah Hyland and Wells Adams' Saturday wedding at Sunstone Winery near Santa Barbara, California, Hyland's cast members from the ABC sitcom were among the guests — and onscreen uncle Jesse Tyler Ferguson shared a particularly sweet moment on his Instagram Story Monday, showing Hyland and TV sibling Ariel Winter sharing a sisterly smile.

"Sisters for-eves," Ferguson captioned the shot of the Love Island USA host, 31, and Winter, 24.

"What an honor to marry my two dear friends @sarahhyland & @wellsadams. I couldn't be happier for you love bugs," he wrote. "I also do Bar Mitzvahs."

Ferguson and Winter were not the other Modern Family stars at the highly anticipated occasion. Sofía Vergara (who brought her son, Manolo Vergara), Julie Bowen and Nolan Gould were also in attendance.

Hyland and Adams first flirted on Twitter in 2016 but didn't get together until the fall of 2017. They got engaged in July 2019, though the COVID-19 pandemic delayed their nuptials multiple times.

Ahead of this weekend's ceremony, Hyland told PEOPLE in July: "I'm really excited to be able to — on paper, officially — start our family."
