When LeAnn Rimes turns 30 on Tuesday, she won’t be missing her 20s one bit.
“Die, 20s, die!” was the theme of the country star’s birthday party, which she celebrated with 20 friends and family members at a private Laguna Beach, Calif., home on Aug. 18.
“I’ve been ready to leave my 20s behind,” she tells PEOPLE. “I had so many amazing things happen in my 20s, and I also had a lot of hard lessons to learn.”
“I really have been truly excited about turning 30. I’m ready to be stronger than ever. It’s a new chapter,” adds Rimes, who shared an exclusive video (above) of her birthday bash with PEOPLE.
Rimes’s husband, Eddie Cibrian, was there to give his wife a kiss after she blew out the candles on a birthday cake, which was topped with a mini-version of Rimes in a bikini standing atop a coffin. “I’m stompin’ on my 20s, stompin’ ‘em out,” she says.
