New York Rehab. Her weight. Her first album. Verbally attacking pop stars like Christina Aguilera. Fighting with her brother on national television. Being a rock star's daughter.
Kelly Osbourne isn't sorry for any of it.
"In order to do something better you have to make mistakes," the 21-year-old singer/actress/aspiring fashion designer said during a recent interview at Sanctuary Records in New York City - shortly before she entered rehab for the second time in as many years.
Osbourne has made a lot of changes in her life - and she's not referring to her numerous hairstyles.
"I have nothing to hide, and I never will have anything to hide," Osbourne said.
Osbourne's sophomore album, "Sleeping in the Nothing," was produced and co-written by Linda Perry (Pink, Christina Aguilera, Gwen Stefani). It's a collection of dance-inducing pop tracks on which Osbourne sings frankly about nearly every aspect of her life.
The result is deeply personal. "Every single person in this world has skeletons in their closet. Including myself," she says. "But when it comes to personal things like boyfriends and the way that I live my life, the world already knows about it, so I don't have anything to hide."
Which is true, considering that the majority of her young adult life took place on MTV's hit reality show, "The Osbournes."
Distancing herself from certain Osbourne stigmas hasn't been easy. "I will never escape that identity," she said. "And that took a long time to come to terms with. That part of my life was a roller coaster, and now I'm moving on and I hope that I get to achieve great things."
Like acting. Having starred in the ABC teen drama "Life As We Know It" last year, Osbourne hopes to someday make movies.
The headstrong Osbourne already knows what she would like to star in - an adaptation of the memoir "A Million Little Pieces," by James Frey.
"I read this book, half of it when I was in rehab (last summer) and half when I got out. It helped me get through it. And the story of this guy, the way that he describes his illness, (it) was very similar to mine."
Osbourne openly discusses her experiences with drug abuse on songs like "Red Light" and "Save Me." But taking a stand against a dark chapter in her life was just one part of Osbourne's experience making this album. Thanks to Perry's support, Osbourne was able to write lyrics about rehab as well as some of her less-than-satisfying romantic experiences on songs like "Secret Lover."
"That was a huge growing experience for me," Osbourne said. "(But) I'm glad that it happened because I felt things that were so deeply painful."
With the release of this album, which Osbourne says is a representation of a "more mature" reincarnation of herself, also comes a truer representation of the girl known as Kelly Osbourne. That, she says, has been the biggest reward.
"I don't think I'm trying to reinvent myself. I think I'm finding myself, being myself ... instead of having somebody telling me what to do."
But don't expect the potty-mouthed Osbourne to become a pushover just because she has grown up.
"I respect my first record because I don't like it," she said. "That album was my learning process. I was a huge marketing ploy. They thought if they signed me they'd make money. They tried to make me like Avril Lavigne or Ashlee Simpson (or) Fefe Dobson. It's just so stupid and fake and contrived, and I never fed into that ... it was sick."
