Zombie Freaks Turn 21: Inside Olsen Twins Bash

Looking like the (poorly-dressed) living dead as always, the lovely Mary-Kate Olsen and Ashley Olsen enjoyed a "full house" on their 21st birthday.

Literally.

More than 150 family members and friends, including Bob Saget, the rest of the cast and most of the crew from the television show Full House - the series that spawned their fame in their infancy - showed up to watch the twins blow.

Out the candles.

Big-time celebrity guests like Joaquin Phoenix and Olivier Martinez were on at the Olsen Twins' party, Us Weekly reports, to celebrate the big event.

Also there was Kirsten Dunst, who was dancing around with pals to the retro rock and roll tunes, which included Blondie and The Kinks. No word on whether or not Razorlight frontman Johnny Borrell, her shaggy purported boyfriend, was there.

Later, Mary-Kate Olsen was seen making out with boyfriend Max Snow, and the two later jumped into the pool together... with their clothes on.

The newly legal duo took great pains to keep out would-be party crashers, closing down the street in front of their house and hiring security to maintain order.

At one point, there was a tearful tribute from family and friends who took turns giving speeches about the oh-so-powerful girls.

"It was really heartfelt but a great time," says a source close to Ashley Olsen and Mary-Kate Olsen. "Everyone danced all night."

Shortly after 11 p.m., Ashley Olsen addressed the crowd.

"I would like to thank everyone who came out tonight to celebrate with me," Ashley said. "I hope we will have many more happy memories this next year."

Ash closed out her speech with some touching words for Mary-Kate Olsen.

"No one could understand me the way you do," said one of the Olsen Twins to the next. "Nobody could relate to me the way you do. In fact no one could tolerate me the way you do!"

She's right - this celebrity gossip site sure can't!
