In the wake of the breakup, which a source tells PEOPLE happened earlier this month, the Scream Queens actress, 29, has turned to her close circle of friends for support.
"Lea is surrounded by her friends, who have rallied around her and support her," says a source close to the couple. "She's doing fine, focusing on her work, her music and her album."
Paetz, whom Michele met on the set of her "On My Way" music video in April 2014, was her first boyfriend after the devastating death of her Glee costar Cory Monteith in 2013.
Michele's rep confirms the split.
