"He was going to propose on the beach during the trip, but he chickened out because he wasn't sure if she would accept," the source said.
Vaughn knew he had to leave immediately to film "Into the Wild" in South Dakota, so he asked her in the private jet before it landed in Los Angeles, the magazine said.
