It's been 15 years since the last episode of the series, and Duff has gone on to star in more shows and became a mom of two, Luca and Banks. The 31-year-old is no regular mom; she's definitely a cool mom, and her 15 tattoos prove that. There's also that time she rocked aqua hair....
Almost all of Duff's classy, tiny tattoos are hidden on the inside of her arms. It takes serious searching to find every one, because they are so small, which is exactly how she planned it.
On an episode of the Ellen Show, Duff revealed a slew of her arm tats.
A green-haired Duff showed off a matching tattoo with her sister that reads "Thick as Thieves" in cursive print. She also talked about her "BK" tattoo that symbolizes the New York neighborhood she lived in while filming Younger.
Plus, she talked about her favorite tat: a little bird with the words "Stand By Me" emblazoned beneath. The actor also joked that in honor of her twelfth appearance on Ellen's talk show, she tatted the host's face on her leg with the number 12 next to it.
