Earlier this year, the supernova hired celebrity trainer Tracy Anderson to help whip her into shape ahead of her wedding day.
She is expected to wed former NFL punter Eric Johnson in the coming months, however she is keeping the details under wraps.
Of course, her former husband Nick Lachey made it down the aisle before her - marrying his girlfriend of four years, Vanessa Minnillo, in an comfortable island wedding on Necker Island on Friday.
As well as her bride-to-be duties and business empire, Jessica has another project in the works.
She will unite the new NBC reality TV series Fashion Star as a celebrity mentor.
