The 33-year-old star married former NFL star Eric Johnson at San Ysidro Ranch in Montecito, California and invited a few of her long-time showbiz pals to attend their four days of festivities.

The 'Sin City' actress, who starred in 'The Love Guru' with Jessica in 2008, was spotted at the couple's Independence Day barbecue on Friday (04.07.14) with her husband, Cash Warren, and daughters Honor, six, and Haven, three.

An eyewitness told E! News that the brunette beauty looked "effortlessly radiant and beautiful," as she spoke to a starstruck teenage guest.

Topher, who bonded with the bride-to-be when she guest-starred alongside him on 'That 70s Show' several times, was also there with his actress girlfriend, Ashley Hindshaw.

After the barbecue, the group boarded buses to the nearby Four Seasons La Pacifica hotel's ballroom and terrace, where they watched a fireworks display.

Speaking about Alba and her family, a source said: "They blended in with other families as they left the fireworks show. Even after a long day, they looked amazing."

The Weight Watchers spokesperson, who announced she was engaged to Eric in November 2010, kicked off their celebrations with a rehearsal dinner on Thursday night (03.07.14) and is expected to host a final brunch tomorrow (06.07.14).

Jessica Simpson bans cameras from wedding

Jessica Simpson and Eric Johnson have banned guests from taking photographs at their wedding at the San Ysidro Ranch in Montecito, California tomorrow (05.07.14), as they have inked a lucrative magazine deal.

The 33-year-old beauty, who married her fiancé Eric Johnson at the San Ysidro Ranch in Montecito, California, has warned her family and friends they won't be allowed to capture any special moments at their nuptials.

A source told the MailOnline that the 'With You' hitmaker, who has two-year-old daughter Maxwell and 12-month-old son Ace with former NFL star Eric, sent a strict email out to her guests, instructing them not to bring any cell phones or cameras to the venue.

The lengthy invitation reads: "Please note that there will be no cell phones or cameras allowed at the wedding location. We kindly ask you to leave your cell phones and cameras in your hotel room or check them in upon arrival with our security team. Security will be checking all guests upon arrival."

The invitation states: "On the 4th of July, guests will be allowed to have their phones and cameras. We look forward to sharing the photos and intimate moments from this day with our guests only. We kindly ask you to refrain from posting images or details on your social networking sites in order to respect and protect our privacy.

"We hope that this weekend leaves you with memories that will last a lifetime."

The former 'Fashion Star' judge, who announced she was engaged to Eric in November 2010, was previously married to Nick Lachey and has hired the same wedding planner, Mindy Weiss, for her second trip down the aisle.

The celebrity party planner said: "I'm really excited about it."

This will also be Eric's second marriage, as the 34-year-old Yale graduate was previously married to Keri D'Angelo for five years before their divorce was finalised in October 2010.
