Jessica recently announced she was engaged to boyfriend Eric Johnson just days after ex-husband Nick Lachey announced his plans to marry again.
And now it has been claimed that the 30-year-old wants to get married by the end of the year.
A source HollywoodLife.com: 'She wants to beat Nick to the altar, she knows that it is going to be tough to pull everything together on such short notice, so it might have to be a New Year's wedding.
'In any case, she wants the focus to be on her wedding, she doesn't want her wedding to be the aftermath of his.'
Jessica and Eric got engaged after five months of dating.
