Jessica Simpson and Eric Johnson ducked into their car after a date at Nobu in LA last night. The twosome are hitting up the hot spots this week, including an evening at the Ivy on the Shore on Tuesday. Jessica is two weeks away from her 31st birthday, so we’ll see if she has another big adventure planned after last year’s luxurious European yacht trip to celebrate the big 3-0. That vacation was one of her first public outings with Eric, and it’s been a landmark year for the couple who are currently planning their wedding. Jessica is also working on her many projects, including a return to TV with Fashion Star this Fall.
