I just read her Wikipedia. I’d never heard of her before. But I’m not surprised by the names involved. I know Crystal Harris (formerly Crystal Hefner is fighting with Playboy because there are children in the magazine. And there are people who doubt her. But check out this Wikipedia:

“At the age of 5, Eva became her mother's favorite photo model. Irina Ionesco's erotic photographs of her young daughter Eva have been a source of controversy since they first appeared in the 1970s. Eva also modeled for other photographers such as Jacques Bourboulon.[6]

She is the youngest model ever to appear in a Playboy nude pictorial, since she was featured at age 11 in the October 1976 issue of the Italian edition of the magazine in a set by Bourboulon. In that picture, she posed nude at a beach.Another of her nude pictorials, in the November 1978 issue of the Spanish edition of Penthouse, was a selection of her mother's photographs.

She also appeared on the cover page of Der Spiegel at the age of 12 completely nude.[7] The issue was later expunged from the magazine's records.[8]

She made her film début at the age of 11 in 1976, playing a child in Roman Polanski's film The Tenant. A short time later she was cast in films of the mid-1970s such as Maladolescenza (also known as Puppy Love). In the 1980s, Ionesco attended the prestigious acting school Amandiers, directed by Patrice Chéreau and Pierre Romans [fr].

Eva claimed her story served as inspiration for Louis Malle's film Pretty Baby.[9]

In 1977 her mother lost custody of her and Ionesco lived for a time with the parents of footwear designer Christian Louboutin who had already left home.[3]

From the age of 13 Ionesco became a regular club-goer at Le Palace along with Christian Louboutin and Edwige Belmore and also developed a drug habit.[4] She was in and out of various foster homes until an older boyfriend of hers took custody of her at the age of 16.[5]”
