According to the source, the couple kicked off with an intimate poolside lunch in their home in Beverly Hills.

Then they moved the party to a more private spot which they referred to as “Camp KuKu” at the Secret Garden at Parrish Ranch in Oak Glen, California.

Their family and friends were in for a bunch of “kid-friendly” activities such as camping and a candlelit dinner of Iowan comfort food, the insider says.

“It was a wonderful day. Just one great party.”

Kunis and Kutcher first met during the set of That ‘70s Show where they were an on-screen couple. Kutcher was actually Kunis’ first kiss.

“We all get movie star crushes. I’m marrying mine,” Mila Kunis muses about her relationship with Kutcher.

Meanwhile, Demi Moore, 52, ex-wife of the former Punk’d host, wasn’t feeling too happy for the couple’s new milestone. Any news about the couple wasn’t welcome in Moore’s home. Kunis and Kutcher’s wedding apparently hurt her so much.

“Demi is heartbroken over Ashton and Mila getting married,” one source says.
