According to reports Jessica Simpson is on a strict weight loss program before her wedding.
Jessica is engaged to Eric Johnson and gave birth to her second child Ace Knute in June.
The pair were forced to cancel their original wedding after Jessica fell pregnant with their daughter Maxwell, who was born in May 2012.
A source said: "Jessica is adamant she wants to be a slim bride."
"She has just over 28lbs to lose. Her goal is to be a UK size 12 for the wedding and at the moment she is a UK size 16. She hasn't set a date but ideally it would be by the end of September."
"Jess is already back on Weight Watchers," an insider continued. "She's desperate to marry Eric this year and be in the best shape of her life."
