Jessica Simpson is getting married around Independence Day.

The 33-year-old singer-and-actress and footballer fiance Eric Johnson - who have children Maxwell, two, and Ace, 10 months, together - will tie the knot over the July 4 weekend in Santa Barbara, California.

And the blonde beauty - who was previously married to Nick Lachey for three years until 2005 - is not planning to walk down the aisle in a traditional white gown.

A source told Us Weekly magazine: ''Jessica is having something unique made. It will be very different from the Vera Wang she wore to wed Nick Lachey.''

Jessica - who got engaged to Eric, 34, in November 2010 after five months of dating - recently admitted her plans have been progressing and she is ''very close'' to issuing invitations for her nuptials.

She said: ''We are very close to sending out our invites. I've been very picky on how I want everything to look and feel. Eric's family alone is almost 90 people, so it'll definitely be a big event.''

Jessica hasn't released new material since her 'Happy Christmas' album in 2010, so she wants to start focusing on her career again after the wedding.

She recently explained: ''We're building a studio in our house. I bought a house from Ozzy Osbourne, so a lot of the studio was already set up. I want to see what comes out. It's time for me to find that out, and I can't wait for my kids to experience that with me. Even Eric. He's never seen me perform onstage.''
