As the U.S. celebrated Independence Day over the weekend, actors Ashton Kutcher and Mila Kunis also had their own celebration as they threw a festive wedding party on Saturday, July 4. 

A source told Us Weekly that the couple offered their guests luxury tents to stay in at the Secret Garden at Parrish Ranch in Oak Glen, California. The venue, which was closed to the public for the special day, was reportedly dubbed "Camp KuKu," and it features acres of apple orchards, ponds, and botanical gardens. According to its website, the gated space only recently became available for exclusive weddings and private events. 

An insider told People that the couple was already legally married, and that the party served as a low-key gathering to celebrate with their loved ones. 

For the occasion, the "Black Swan" actress reportedly wore a strapless tulle dress with crystal beading detailing and a low cut back. An eyewitness told Us that Kunis had her hair in a bun and "was a glowing and stunning bride." Kutcher donned a dark suit, while their daughter, 9-month-old Wyatt, was garbed in an "adorable" white dress. 

The insider said that Kutcher doted on his daughter and was carrying her around throughout the afternoon. 

"He clearly loves her so much and never wanted to put her down," said the source, adding that Wyatt was perfectly behaved throughout the ceremony and "didn't cry or make a fuss." 

Another source told E! Online that the party went late into the night on the Fourth of July. 

"Everyone danced and had a great time," said the source. "There was also a casual farewell brunch on Sunday morning before everyone went home." 

Kutcher and Kunis have known each other since starring on "That 70's Show," which aired on Fox from 1998 to 2006. The two didn't start dating until April 2012 and they got engaged in February 2014. The pair welcomed their first child, Wyatt Isabelle, in October. This is the first marriage for Kunis and the second for Kutcher, who wed Demi Moore in 2005. Kutcher and Moore separated in November 2011 and he filed for divorce a year later.
