The 30-year-old singer and actress - who announced her engagement to former NFL player Eric Johnson in November - has invested in a number of cookery books and is learning how to whip up animal product-free culinary delights at the Madeleine Bistro in Tarzana, California.
However, it would appear this is a new passion as the blonde beauty`s ex-husband Nick Lachey - who Jessica divorced in 2006 after four years of marriage - didn`t benefit from her domestic skills.
A source told National Enquirer magazine: "Jessica is determined to be more of a domestic goddess this time in regards to her marriage.
"She hardly ever prepared meals when she and ex-hubby Nick Lachey were together."
It could be the `Public Affair` hitmaker is honing her skills to prepare for a family with her new fiancé, as she recently admitted she is keen to have kids with Eric.
Jessica said: "I definitely see myself having a family with Eric, so that`s exciting to think about."
