Alison Arngrim — Age 59

Whoa! That’s Nellie Oleson? Yes, and she’s aged flawlessly! The Little House on the Prairie character was played by Alison Arngrim, who is now 59 but still has the same bright blue eyes. For her portrayal of Nellie, the former child star even received a Lifetime Achievement Award.

Although she hasn’t had a more impactful role as on Little House, Arngrim is still hard at work in showbiz today. In 2010, she released a controversial autobiography that gained critical acclaim for mixing humor with personal tragedy seamlessly. In 2021, we can expect Arngrim in the family film Even in Dreams.
