Calista Flockhart

Technically speaking, Calista Flockhart is no longer a single mom. However, there was a point in her life that she had to fly solo raising her son, Liam.

With the help of her lawyers, the Brothers and Sisters actress adopted her son, Liam, back in 2001. Soon after the actress took Liam in, she quickly retreated from the spotlight to focus her attention on raising her son. Then, by 2002, Flockhart crossed paths with veteran actor Harrison Ford and soon began dating. Right off the bat, Harrison assumed the father role for Liam. He even opened up about their family setting and commented that his wife of 11 years has done an incredible job raising Liam. Flockhart’s son is all grown up now and is on his way to college. The family recently made headlines when they were spotted taking a stylish private plane to help Liam move into his dormitory.
