Jennifer Lawrence's wedding was the place to be for celebs on Saturday.

The 29-year-old actress married her beau Cooke Maroney on the grounds of the Belcourt Mansion in Rhode Island, at dusk, in front of 150 people, including her BFFs Adele and Emma StoneAmy SchumerKris Jenner and Corey GambleAshley OlsenNicole Richie and husband Joel MaddenCameron Diaz and husband Benji MaddenSienna Miller, and David O. Russell, who directed the bride in the movie Silver Linings Playbook, which earned her an Oscar.

"Guests were greeted on a lawn with cocktails served in copper mugs," an eyewitness told E! News. "The wedding had all the touches of fall with dark colored flowers, apples in baskets and open fire spits roasting beef. All the food was prepared outdoors with wood roasted fish and heirloom roasted carrots and squash as part of the menu." 

The bride, a celebrity spokesmodel for Dior, wore a wedding dress by the brand, while the groom wore a black Dior tux. 

After the ceremony, guests headed indoors for a reception. They ate dinner at long tables. The food was served family style.

And don't forget about the dancing.

"They had a DJ and everyone danced for hours," the eyewitness said. "They played all the classics from Jackson 5 to Aretha Franklin. Nobody wanted to leave. Many stayed until 2 and 3 a.m. Corey Gamble visited the Boston's Baddest Burger food truck and got burgers and fries for him and Kris as they waited for their car."

"It was an all night party," the eyewitness continued. "Jennifer and Cooke didn't leave Belcourt until 5:30 a.m. They were the last guests to leave. The looked very happy but tired. Jennifer had on a long sleeved jeweled dress. Her hair was up with strands framing her face."

The bride and groom spent their wedding night at a rental house a few miles from the venue, while their families stayed at properties nearby, E! News has learned.
