Thirteen years ago, the TV personality hosted the MTV Movie Awards pre-show, and on Sunday, viewers will see her back on the carpet interviewing Hollywood's biggest stars as the network's official red carpet host alongside Jessie J and Josh Horowitz.
"It's really scary and it's really exciting. I get to be more creative and pick the questions and talk about fun things and not necessarily just be so focused on look," Osbourne tells PEOPLE exclusively of her first post-Fashion Police gig.
Since quitting the E! Show in February after co-host Giuliana Rancic received flack for comments she made regarding Zendaya's dreadlocks, the TV personality, 30, has been taking her time figuring out the next steps of her career.
"I have been offered every single job you could think of in this time, and some of them I thought a year ago would've been my dream job, but today I don't know," says Osbourne, who is currently working on a book and various beauty and fashion lines, among other projects. "I realized how consuming one job can be because that was my entire universe. When you remove yourself from that, you realize there's more out there."
Osbourne, 30, has also been enjoying time with her family and friends in the past few weeks.
"I've been working for six-and-a-half years nonstop," she says. "Every family vacation, I never had enough time off work to go because I wanted to make my own life and do my own thing, so I made sacrifices. I actually just went to one of my friend's bachelorette parties, and it was the most fun."
And though she's feeling "anxiety" about stepping back onto the red carpet on Sunday, Osbourne is excited "to do different things."
"I want to make people feel good, and I want to have fun," she says. "I don't want to feel like I've hurt people's feelings or I've done something wrong. I just want to make this amazing."
The MTV Movie Awards will air live on Sunday at 8 p.m. ET from the Nokia Theatre in Los Angeles.
