Sitting in a cozy booth at the Hominy Grill in Charleston, S.C., on May 3, Reese Witherspoon and Jake Gyllenhaal were the picture of happiness. Though the cheery couple, who arrived holding hands, brought their appetites, their minds weren’t on food.

“They couldn’t keep their eyes off each other,” Hominy Grill manager Brandy Mangum tells OK!. “The entire time, he was so attentive. It was really sweet. They really do make the perfect couple.”

Friends of the pair say it won’t be long now before Jake pops the question to his lady love. “They’ve been talking marriage for a while,” a source close to Reese reveals to OK!. “They’ll be formally engaged any day now. They want to spend the rest of their lives together.”

But don’t expect these two to go down the route of so many Hollywood couples who move in together and start families before getting hitched. “This is a very serious relationship,” the Oscar-winner’s pal explains. “But Reese is very conservative and traditional. I’m sure she doesn’t want her kids to see her ‘living in sin.’”

When asked about their clients’ plans for walking down the aisle, Reese’s rep had no comment, while Jake’s people claim there are no immediate plans for a wedding.
