Jamie-Lynn Sigler is sporting a new 'do!
The "Sopranos" actress celebrated her 39th birthday on Friday by cutting off two years of hair growth.
"That's 2 years of physical, emotional, and spiritual growth that I cut off right there on my bday, thanks to some 'help' from my sis @riawna," she captioned an Instagram photo, referring to a Zoom session with hairstylist Riawna Capri, who coached her through the cut.
Jamie-Lynn, who proudly held up her now-shorn ponytail in the picture, plans to donate her locks to the BeYOUtiful Foundation hair donation program, which was created for women battling cancer.
The foundation posted the same photo of the actress, writing, "One of our biggest supporters and absolutely one of our favorite people. @jamielynnsigler wishing you the happiest of birthdays. Thank you for the years of love and support, it means everything. Oh and a little #zoom help from @riawna never hurts."

Because the chop came on her birthday, Jamie-Lynn thanked friends for their well-wishes.
"To everyone who came by today, sent food, flowers, videos, FaceTimes… thank you so much," she wrote on Instagram. "It's nice to feel grateful during times like these. This is #39."
