EXCLUSIVE: Jamie-Lynn Sigler's Wedding Dress Is Absolutely Gorgeous -- See the Pics!

Jamie-Lynn Sigler and Cutter Dykstra are officially husband and wife, and their desert-chic wedding was one for the ages!

The longtime couple tied the knot at The Parker Hotel in Palm Springs, California, on Saturday, and the Sopranos alum looked absolutely stunning in her sleeveless, A-line Oscar de la Renta wedding dress.

The gown featured a sweetheart neckline and tulle petticoat. The bride wore her hair up, with just bangs peeking out of the updo, and a long veil attached to her bun.

Dykstra -- an MLB pro who most recently played for the Washington Nationals' Triple-A affiliate in Syracuse, New York -- was no slouch either. The groom looked equally as handsome in a black Brooks Brothers suit and matching bow-tie.

About 150 guests attended the outdoor nuptials, which Sigler, 34, and Dykstra, 26, kept classic with a black-and-color scheme, including white flowers.

Adorably, the actress and athlete's 2-year-old son, Beau Kyle, as well as their dog, Bean, were part of the ceremony, which was officiated by Sigler's BFF, Lance Bass. It was a sweet testament to the pair's friendship, as Sigler had helped officiate Bass' wedding to husband Michael Turchin in 2014.

The former *NSYNC band member -- who looked dapper during the affair in a dark gray suit -- arrived in Palm Springs Friday night, and he shared a snap of his feet on social media, asking fans which if he should wear space or sloth socks to officiate his first ceremony.

Almost every one of his fans responded that they wanted him to don planets on his toes, which he did end up doing, while Lisa Vanderpump tweeted at him to not wear a onesie.

Bass wasn't the only famous face at Sigler and Dykstra's nuptials -- actress Joanna Garcia (the other officiant at Bass' wedding, alongside Sigler) and her husband, Atlanta Braves first baseman-outfielder Nick Swisher, made the trip out to the desert, and some of the girls got ready in Garcia's hotel room. Lea Michele was also in attendance, arriving in Palm Springs around lunchtime. 

During the 30-minute ceremony, which started at 4:30 p.m., the couple recited their own vows. A string duet performed classics by the Beatles, Cyndi Lauper and Elvis Presley, including Presley's hit "Fools Rush In." The guests gave the newlyweds a big round of applause at the end of the "I do's."

The couple thoughtfully provided guests with blankets in case they got cold -- those nighttime temperatures can really dip in the desert! -- but they were also able to warm up inside the reception at the hotel.

Sigler and Dysktra were first introduced by Swisher, and they got engaged in January 2013. They welcomed Beau that August.

Congratulations to the happy couple!
