Shanna Moakler made the best of her split from Travis Barker on Friday with a divorce party
at the Las Vegas nightclub Light at the Bellagio.
"I've been to past friends' divorce parties so I'm not the first person (to have one)," she tells PEOPLE. "I'm not groundbreaking or anything. I'm really doing it for myself to have closure and celebrate being single again and start a new chapter in my life."
The former Meet The Barkers
star and Dancing with the Stars
contestant hung out with a group of girlfriends all night, moving to various tables all around the club to get different perspectives.
Finally settling on a corner booth, Moakler joined an existing party's table to hang for the night. Wearing a short black dress, she was clearly having a good time as she drank vodka and did shots with her newfound friends.
The highlight of the evening came at dinner, when the Ballagio's Fix restaurant brought out a "divorce cake" for Moakler. The three-tiered cake featured a miniature knife-wielding blonde in a wedding dress on top, with a trail blood leading to a tiny groom sprawled at the bottom.
On hosting the oddly themed bash, Moakler tells PEOPLE, "I don't have any regrets about doing it. I am who I am and I make my own decisions. I totally respect people's opinions. I never thought I would be getting a divorce. I never thought I'd be here. At the end of the day, this isn't the worst thing in my life. People go through it every day. I respect people's opinions, but this is my opinion. This is how I'm showing the world that divorce is okay. I doesn't have to be the end of your life."
Barker, 30, the former drummer for blink-182, filed for divorce
from Moakler, 31, in August.
