This isn't the first time Winter has worked with Dr. Woo. Earlier this year, she showed off a script tattoo on her right thigh reading "Love Risks Everything And Asks For Nothing" in Greek.
"Peep tattoo 1 of 3. @_dr_woo_ is a master," she wrote.
She also has the initials of her four nieces and one nephew displayed on her ribcage. So far, Winter has not revealed what her third tattoo is.
Winter also took to Instagram on Sunday to wish her Modern Family co-star, Sofia Vergara, a happy 44th birthday.
"A true throwback with this beautiful lady for her birthday!!!" Winter captioned a super cute picture of the two taken during the early days of their hit ABC show. "Happy birthday Sofia! You're such an amazing woman and I'm so grateful to know you! I love you ❤."
