Macklemore and his partner, Tricia Davis, are parents! The couple welcomed their baby girl [1], Sloane Ava Simone Haggerty, at the end of May, and the rapper — whose real name is Ben Haggerty — took to his website to share the news on Wednesday. "There is nothing like the joy and happiness that comes from bringing a baby into this universe," he wrote, adding, "She has filled my heart in ways that I never knew were possible. She is the love of my life."

Along with the sweet birth announcement, Macklemore also debuted a new song [2] in honor of his newborn daughter titled "Growing Up." It's the first new music from him and DJ Ryan Lewis since their Grammy-winning album The Heist and features vocals by Ed Sheeran; the song's lyrics detail Macklemore's dreams for his baby girl, including, "They say girls shouldn't be tough and moms should raise their kids at home / But baby I know that that isn't true, cause your mama's the toughest person I know." Listen to the song below now — congrats to Macklemore and Tricia!
