Finally, their happily ever after!

After four years (and two babies) together, Jessica Simpson married fiance Eric Johnson in Montecito, Calif. on Saturday, July 5, Us Weekly can confirm. The couple said "I do" at the lavish San Ysidro Ranch.

Simpson, 33, and the former NFL player, 34, were feted by their closest family and friends, including the singer's parents Joe and Tina Simpson, sister Ashlee Simpson and fiance Evan Ross, CaCee Cobb and husband Donald Faison, and Jessica Alba and beau Cash Warren. Ashlee and Cobb were bridesmaids for the special occasion. The couple's daughter Maxwell, 2, and son Ace, 13 months, also played special roles.

During the ceremony, an instrumental version of Chris Isaak's "Wicked Game" was played, according to an insider. At one point, cheers and claps erupted from the covered tent, which were decorated with stunning chandeliers.

Simpson and Johnson made it a fun-filled weekend for their guests, as they kicked back and relaxed with a good old fashioned BBQ to celebrate the Fourth of July a day earlier. Guests danced, sang karaoke, and played outdoor activities like corn hole, horseshoes and croquet. "They all seemed to be having a really good time!" an insider told Us.

As previously reported, Johnson also snuck away to play a round of golf with some of his bros at Sandpiper Golf Course in Santa Barbara on July 3. "They were a really attractive group!" an eyewitness told Us. "They played 18 holes and drank lots of Bud Lights!"

Father-of-the-bride Joe Simpson was also included in the outing. "There were definitely a lot of Southern accents. The guys were all super hot!" a second onlooker added. (The Simpson clan hails from Texas.) "They had a really good time."

Last month, the couple similarly let loose with pals at a joint, co-ed bachelor-bachelorette bash at Eveleigh restaurant in West Hollywood. "They were having a great time. Jessica looked absolutely amazing-and tiny," a source said. An onlooker noted: "Jessica looked very cute sitting next to Eric. He had his arm around her shoulders, and I saw them kiss."

Simpson and Johnson got engaged after nine months of dating in November 2010. The couple put their wedding on hold twice, but for two very good reasons. In May 2012, the pair welcomed their baby girl. Six months later, Us broke news that the mom was expecting again. Son Ace arrived that June.

This is the second marriage for both. Simpson was previously married to Nick Lachey from 2002-2006. He married TV personality Vanessa Minnillo in 2011, with whom he shares son Camden, 22 months. Johnson finalized his divorce from stylist Keri Johnson after five years of marriage in October 2010. He and Simpson met while he was separated, but still legally married.
