The 18-year-old actress is graduating from Campbell Hall School, a private high school in Studio City, California, on Monday. In April, she revealed she's attending college at the University of California, Los Angeles (UCLA).

"I love UCLA. Everyone in my family loves UCLA. It's an amazing school," Winter told ET last month at Modern Family's Emmy consideration event in Los Angeles. "The college process was so long and just really, really insane. But at the end of the day, I'm so happy with UCLA."

"When I got the acceptance letter I literally just sat and cried staring at my computer," she added, also sharing that she'll continue to act while in school.

Graduation isn't the only big milestone Winter's recently celebrated. Last month, she attended her senior prom in a lacy black strapless gown with a friend, after recently splitting with her now ex-boyfriend, Laurent Claude Gaudette.

Aside from her school activities, Winter is currently filming Burt Reynolds' upcoming dark comedy, Dog Years, in Knoxville, Tennessee. Reynolds, 80, plays an aging, former movie star in the film, who is forced to realize that his glory days are behind him.

... And it's safe to say Winter's skin-baring costume on set is pretty jaw-dropping.
