The black-and-white photo, posted Wednesday, shows a hummingbird on her hand and the actor's birth date (7-21-51) on her wrist.
"For poppo," she captioned the image, thanking the tattoo artist for "so beautifully bringing my reminders to life." She added, "I'll always put my hand out to shake with a smile."
"As for this Instagram, I don't know in what capacity I'll continue using it in the future, but I'm leaving it up regardless so that fake accounts hoping to use my name or misuse my family's photos will get no traction," she wrote. "To be clear, this is MY ONLY account. Publicly, I have Twitter, and this. If other people post quotes and photos claiming to be me or my family, please, do not send them personal information or click links, even for charity. They could be utilizing sympathy to scam you. For the record, no one has ever or will ever speak for me but me. Thank you."
