Nick Lachey Throws Birthday Bash For Jessica Simpson

People magazine reports that on July 11th, 98 Degrees star Nick Lachey hosted a 23rd-birthday bash for his wife Jessica Simpson at the Concorde in Los Angeles. Four hundred of the couple’s friends, including Jessica Alba, Pink, Jessica Biel, Lance Bass of *NSYNC, Seth Green, and Taye Diggs, showed up at the soiree, which had a Mad Hatter’s tea party theme. Playing cards dangled from the ceiling and rose-filled teapots decorated the tables. The highlight was the cake: a gigantic butter-cream-and-raspberry-filled concoction. “She had a smile on her face the whole night,” one attendee remarked.
