With all the chaos in the Gallagher household, it can be challenging to keep track of the Shameless characters’ ages from the beginning to the end of the show. When the comedy-drama series debuted on Showtime in 2011, all the Gallagher kids, except for Fiona, were still minors. By the time the series wrapped up with the season 11 finale in the spring of 2021, all except Liam were adults with jobs and, in some cases, kids of their own, showing the incredible timeline of the long-running show.
