Birthday girl Jaime Pressly has never been afraid of experimenting with her looks. The actress, who turns 39 today, has rocked everything from a side-shaved faux hawk to playful auburn lowlights, deep brunette strands, and the platinum blonde layers and blunt bangs we recognize from her Emmy-winning portrayal of the hilarious Joy Turner from My Name Is Earl. Since that role, Pressly has been keeping up the pace: In 2016, she was cast once again as a series regular on CBS comedy Mom with Anna Faris. In March, the series was renewed for a fourth season, which is scheduled to premiere on Oct. 27, 2016.
When Pressly isn’t busy shooting her TV show, she’s busy playing mom IRL to her 9-year-old son Dezi James. Despite her busy schedule and many mom duties, Pressly always manages to look great (and totally ageless). In honor of her special day, take a peek through Pressly’s best beauty looks and see how they've evolved through the years.
