Kelly Osbourne Celebrates 40th Birthday With Star-Studded Chanel-Inspired Party: See Photos

Move over Chanel No. 5, because it's all about Kelly No. 40.

Kelly Osbourne celebrated her milestone 40th birthday on Friday, November 1, with a blowout bash held at Los Angeles' W Hotel.

All decorations were coordinated by Bonjour Fete, who made sure to capture Osbourne's love of Chanel with black, white and pearl accents throughout the room. The venue also featured over-the-top balloon arches, candles and a tiered cake befitting the theme.

"I am just so grateful for every mistake I made, for every lesson learned, for all of it. I have such an incredible life," Osbourne exclusively said in her cover story , which hit newsstands earlier this week. "I truly believe my baby saved me and made me a whole human."

The TV personality shares son Sidney , who turns 2 later this month, with partner Sid Wilson. Baby Sidney was among Osbourne's family at the party.

Other guests included Shanina Shaik, Brenda Song, Lucy Hale, Raven-Symoné, Carter Jenkins, Alessandra Torresani, Rachel Lindsay Dylan Mulvaney. An eyewitness exclusively tells that Osbourne "lit up" and "nearly jumped over the couch" to hug model Shaik upon her arrival.

Attendees enjoyed a photo booth by Pop Social and took home gift bags from The Crème Shop (which included a copy of Osbourne's Us Weekly cover issue, currently on stands now!).The party was hosted by several of Osbourne's friends: actor Daniel NgyuenBrooke Lester of boutiques White Trash Charms and Ruski Candles, IFP Communications founder Melissa Rosenfield, and Jeff Beacher of Las Vegas' Beacher's Madhouse.
