Jessica Simpson looked pregnant in a form-fitting bridesmaid dress at CaCee Cobb's wedding to Donald Faison over the weekend. Simpson's personal assistant tied the knot in California. Jessica was one of CaCee's bridesmaids. Jessica's separated parents, Tina and Joe and fiance Eric Johnson and her sister, Ashlee Simpson also attended the ceremony.  Meanwhile, it seems that CaCee reportedly stole Jessica's wedding spotlight. Jessica reportedly got so involved with planning CaCee's wedding that she wasn't able to tie the knot to her own fiance in 2012 however, now rumors are swirling that Jessica and Eric are planning to elope over a Christmas holiday.  According to Perez Hilton, a source said, "No one quite knows what is being planned, but family members are speculating that they could be planning a surprise wedding. Jessica and Eric had planned to get married before the end of the year, but because Jessica was helping her best pal Cacee with her wedding she got sidetracked. Then, her father's problems shattered her world and she discovered she was expecting. Jessica is certain though that she wants to get married before her baby is born, and isn't bothered if she's showing in any wedding pictures. She just wants a relaxed and intimate ceremony and has been dropping hints that the big day could be right before Christmas."
