A representative for the actress – who plays Haley Dunphy – confirmed that she and actor Matt have parted ways after a five-year relationship.
A source told E! News that the split was amicable, adding: "She is having a good time right now. They thought they would be better off as friends."
Sarah, 23, and Matt, 24, initially met during an audition for Disney movie High School Musical and romance blossomed from there. Before they split they had been living together in LA and owned a dog.
Brunette Sarah hasn't referenced the break-up on her Twitter account, instead focusing on the fun of the Emmy Awards this week, where Modern Family won in the 'Outstanding Comedy' category.
"Very happy to have spent the night with my friends who happen to be the greatest team ever!" she tweeted, alongside a photograph of her laughing on the red carpet.
