Melissa Etheridge
In the ‘90s, Melissa Etheridge and her then-partner, Julie Cypher, had two kids thanks to a sperm donation from their rocker friend, David Crosby. After Melissa and Julie’s split in 2001, Melissa became involved with Tammie Lynn Michaels, who later gave birth to twins. Though the couple split in 2010 and fought over custody, they eventually agreed to share custody in 2012.
