Ariel Winter quotes Beyonce.

Trouble in paradise?

Ariel Winter hinted that she may be single again, attending her senior prom over the weekend without her longtime boyfriend, Laurent Claude Gaudette. Winter shared gorgeous pics of herself headed to the big event on Monday, including one in which she tellingly flips the bird and quotes the sassy lyrics to Beyonce's "Sorry."

"Middle fingers up, Put them hands high. Wave it in his face, Tell him boy bye," she wrote.

The 18-year-old Modern Family star looked stunning in a strapless black mermaid gown, leaving her bright red hair down.

She also posted a pic with her dad, who adorably saw her off.

Winter wasn't dateless on her big night, opting to go with friends.

Meanwhile, Gaudette shared some cryptic poetry on Monday, posting a dramatic pic of himself on Instagram.

"Let me love you. Let me haunt you. Let it reward you. Let it taunt you," he wrote. "Present in the moment, get on with the day. With new cards dealt, it's my turn to play."

Last April, Gaudette accompanied Winter to her prom, in what appears to be happier times.

The last time the couple was spotted together was last month, when they went to Coachella.

Winter and Gaudette have actually broken up before. In December, she again quoted a Beyonce song on Instagram -- "Single Ladies" -- to announce the breakup. "Start of a new week, start of a new chapter #dancinglikebeyoncemood," she wrote at the time.

Winter certainly has lots to look forward to these days. The actress is headed to the University of California, Los Angeles (UCLA), and couldn't be more excited about going off to college.

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