Jessica Simpson had her Birkin bag and her man, Eric Johnson, by her side over the weekend as she boarded a private plane out of LA. Jessica has been spending most of the Summer in California with her fiancé, and she recently got to celebrate her best friend CaCee Cobb's own engagement to Donald Faison. Last week, Jessica and Eric took in an Adele concert with fellow celebrities like Robert Pattinson, and they've also been bonding with Eric's parents and Jessica's family in recent months. Jessica is making the most of some downtime before she heads back to TV this Fall with her reality series Fashion Star. She's enlisted fellow celebrity-turned-designer Nicole Richie for her stylish new endeavor, and the pair will judge and mentor the contestants on the show. Jessica's focus is on the new project in the weeks leading up to its debut. She recently said she doesn't have a wedding gown picked out, and she and Eric have yet to announce a date, though the engaged duo are still clearly inseparable.
