Since Michele and Paetz's breakup, which a source exclusively revealed to PEOPLE happened earlier this month, the Glee alum has been focusing on her career and turning to her close friends for support.
"Lea is surrounded by her friends, who have rallied around her and support her," a source close to the couple said. "She's doing fine, focusing on her work, her music and her album."
The two met in 2014 on the set of Michele's music video for "On My Way" and dated for two years.
Paetz was Michele's first boyfriend after the sudden death of her Glee costar Cory Monteith in 2013.
