Thadki Hefner getting hitched to 24-year-old Crystal

Today in Tweet Beat, Hugh Hefner posts a photo of the invitation to his wedding to Crystal Harris. Plus, Joan Rivers and Sandra Bernhard hang out.

Worldwide icon and founder of Playboy magazine, Hugh Hefner, 84, will exchange vows with Crystal Harris all of 24 years on June 18 and Harris revealed that she will not be dressed in white for the wedding. Instead, she paid tribute to her husband to be wearing the color pink signature of Playboy. She told, “dress is not white. I love the pink! That dress is pink and the HEF, and I want that marriage is just a lot of different colors and beautiful.” The couple also ordered a strawberry cake and flowers in fuchsia and turquoise.

Crystal Harris (born April 29, 1986) is a British-born model and singer who was the Playboy Playmate of the Month for December 2009. She became one of Hugh Hefner’s girlfriends and moved into the Playboy mansion in late 2008. They announced their engagement in December 2010.

“A June bride. It will be at the Mansion but it will be a little more intimate,” Hugh flattered. “My brother will be my best man. The groomsmen will be my two youngest sons, Marston and Cooper,” said Hugh. “The bridesmaids are my best friend, Ana, as my maid of honor, and my two sisters are going to be my bridesmaids,” added Crystal. Miss Harris was proposed as well as gifted a giant diamond ring by Hufner on 2010 Christmas Eve. At the time Hufner tweeted, “This is the happiest Christmas weekend in memory….Yes, the ring I gave Crystal is an engagement ring. I didn’t mean to make a mystery out of it.” According to UsMagazine, Crystal Harris has already began searching her wedding gown, and is said to be eyeing a strapless dress by designer Romona Keveza. The weekly also said that there will be less than 300 guests to be invited.
