She declined to appear on her own family’s reality show and consciously avoids the spotlight, so you’d be forgiven for not realizing there was another Osbourne daughter.

But that might all be about to change for the eldest daughter of Sharon and Ozzy, 31-year-old Aimee, who is now launching a music career.

Aimee, the big sister of Kelly and Jack, was just 16 when she opted not to take part in "The Osbournes" because she says she always knew she wanted to be a singer.

The reality TV show catapulted the rest of her family to instant fame, particularly younger sister Kelly, who has made her mark on the fashion world and co-hosted E!’s "Fashion Police" until earlier this year.

In an interview with Rolling Stone, Aimee revealed she is releasing her music under the name ARO to avoid “the obvious associations” with the Osbourne name.

“I don’t think I will ever cross-contaminate my private life and my family life with my public and professional worlds,” she told the magazine.

“For me, nothing’s more important than having a very clear boundary between the two. That’s just part of who I am.”

In March, ARO released a music video for her single "Raining Gold" and is planning the release of an EP in the coming months.
