Jessica Simpson mixed things up in a tight, black sequined dress for last night's NBC TCA party in Pasadena, CA. Jessica was coming off a long day of press, but she was still in great spirits — and extremely high, spiky heels — to stop by the bash. Earlier in the day, Jessica joined Nicole Richie to talk Fashion Star, their new reality show which is coming this March. Jessica also revealed her plans for a maternity line, something she's an expert on now that she's expecting her first child with fiancé Eric Johnson. Jessica and Eric make up one of the many engaged celebrity couples, though they are saving their "I dos" until after the arrival of the baby.
