Ireland Baldwin, the daughter of Alec Baldwin and Kim Basinger, showed off an interesting tattoo earlier this week on Instagram that’s raising some questions around the web.

The 18-year old model snapped a photo of herself lying in bed with one arm thrown up to reveal her new ink, which is of a bra with a bow in the middle. Is it in support of breast cancer survivors? Does she just really love lingerie? Baldwin didn’t really give us much to go on, choosing instead to caption the photo “zzzzzzzzz”. And while many thought the new tattoo was a lovely addition, others commented on the photo saying they hoped it was a fake.

The teen beauty has a total of four tattoos now; the word “Truth” on her neck, an arrow on her arm, a lotus flower, and the bra. The neck tattoo was her first, and she got it when she was just 16.

Baldwin posted a photo to the image sharing site last month of herself with her new baby sister, Carmen. The 5-month old is the daughter of Alec and wife Hilaria and was the subject of a patdown at the airport recently, much to Alec’s irritation.

“Flying from Nassau, Bahamas 2 NY. TSA ‘random selects’ my 5 month old daughter 4 a pat down #travelinginUSisadisgrace,” he wrote.
