LAX hosts Criss and Holly’s joint birthday bash

Criss Angel turns 41 years old today and he’ll celebrate tonight in pure Vegas style with his girlfriend, Holly Madison.

While 41 isn’t a landmark for most people, it presents Angel with an interesting coincidence: He is now half the age of Madison’s ex, 82-year-old Hugh Hefner.

The blonde bombshell and the Playboy mogul ended their years-long relationship a few months ago.

Madison recently moved out of the Playboy mansion’s master bedroom and into her own condo in L.A. – not that she’s there all that often. She has been spending much of her time in Las Vegas ever since she and the Mindfreak magician went public with their romance.

While the two denied their romance early on, they have been publicly dating for seven weeks now.

“Madifreak” recently returned from a two-day getaway to Disneyland.

“I’ve never been to Disneyland in my entire life, never, ever, ever, ever, never,” Angel said before the trip. “I’ve always wanted to go but I just haven’t had the opportunity.”

Back in town, both are ready to party.

The couple was born 12 years and four days apart – Madison will celebrate her 29th birthday on Dec. 23 – so tonight’s soirée at LAX is being billed as a joint birthday bash for the pair.

But because even bad boy magicians have to work on their birthdays, Angel won’t show at his own party until after the second performance of his Cirque du Soleil show, Believe, lets out.

Madison’s former housemate and “Girls Next Door” co-star, Bridget Marquardt, will also make an appearance in the VIP section at LAX tonight.

Madison will see another former friend and house bunny on Saturday when the third “girl next door,” Kendra Wilkinson, joins her and Marquardt at an book signing session at Caesars Palace.

The mini-reunion was arranged as part of a promotional event for the new Girls Next Door book that was released earlier this week. Quality reading just in time for the holidays – looks like we know what Angel is getting for his 41st.
