Ariel Winter and longtime boyfriend Laurent Claude Gaudette have broken up, a source close to the actress confirms to ET.
The Modern Family star hinted at the news when she posted a meme from Beyonce's "Single Ladies" video to Instagram on Monday, writing, "Start of a new week, start of a new chapter #dancinglikebeyoncemood."

While it was entirely possible that the 17-year-old actress could have just been getting her Queen Bey on, the song choice was certainly curious for the couple, who have otherwise seemed totally solid in their relationship.
The two have often appeared posing together and showing PDA, like in October, when Ariel wrote, "My Czech shmooey spending a weekend with us Greeks for the wedding."

Meanwhile, Ariel has become a voice against online bullying and harassment this year after undergoing a breast reduction surgery in early June.
"“I typically never give power to the mean things people bravely say behind their computer screens on the Internet, but this is for the girls who are constantly bullied whether it be online or at school,” she wrote in November. “You are not asking for anything because of what you are wearing- you are expressing yourself and don't you ever think you deserve the negativity as the consequence to what you are wearing- YOU ARE BEAUTIFUL.”
