Our 31st bday bash on Saturday night was the best birthday party we have EVER had!!!!!
The legendary Viper Room on Sunset Blvd was filled with our closest friends and family and some really good music!
Miz Christina Aguilera was our surprise performer for the evening, delighting the crowd with her fierce vocals and even fiercer divaliciousness!
The Jonas Brothers surprised Perez by presenting him with his birthday cake and an acoustic guitar signed by the group.
And, for the second year in a row, the a-m-a-z-i-n-g DJ Mighty Mi kept the energy high with his super skillful song selections!
Revelers included Amanda Bynes, Ashley Tisdale, Aubrey O'Day, Brittany Snow, Brittney Gastineau, Christina Aguilera, Cisco Adler, Dean and Dan Caten, Diane Warren, Doug Reinhardt, Dr. Luke, Emmy Rossum, Ferras, Heidi Montag, Jamie King, Jeppe, Jessica Stroup, Jonas Brothers, Kim Kardashian, Lacey Schwimmer, Meghan McCain, Meiko, Paris Hilton, Pia Glenn, Robin Antin, Ross Mathews, Salman Rushdie, Schwayze, Spencer Pratt, Steve-O and Tara Reid.
What an eclectic group of people, huh?????
Our 31st OMFG could not have been made possible without the help of Bruce Starr and everyone at BMF Media Group, Ben Russo and everyone at EMC PR and our amazing sponsors: 5 Gum, Alize, Belvedere IX, Café Bustelo, Cold Stone Creamery, Dos Equis, Fiji Water, FUZE Beverage, Gordon Ramsay's, Ookisa, Red Bull, The London Hotel, YMI Jeanswear and Zirh.
We almost had too much fun at our party! It was sad when it was over because it felt like it happened so quickly.
A few blinks later and the party was over!
But, it's special moments like our birthday bash that make all our hard work worth it, and it helps us to realize how lucky we are and how much we appreciate every moment.
Tomorrow is not guaranteed!
Make today Perezcious!!!!!
