Dominic Purcell's son Joseph Purcell isn't just a fellow actor - he's also an internet sensation thanks to TikTok's popular vertical dramas. Dominic shares four kids with ex-wife Rebecca Williamson, whom he married in 1998. The pair welcomed Joseph in 1999, followed by daughter Audrey in 2001 and twins Augustus and Lily-Rose in 2003. Dominic and Williamson called it quits in 2008, and the Prison Break alum has since tied the knot with Tish Cyrus.
