Bride-to-be Jessica Simpson is going to have the merriest Christmas ever!
"This is the happiest she's been in her entire life," her dad Joe Simpson told UsMagazine.com at Wednesday's launch party for his show The X Life.

Simpson, 30, and ex-NFL-er Eric Johnson, 32, got engaged last month after a whirlwind 5 1/2 months. (Popping the question in her L.A. home, Johnson surprised her with a $150,000 ruby-and-diamond ring.) "It's so wonderful to see," Joe gushed.

"She is in love and I know she will have so many love songs to write straight from the heart for her new record."

Joe had high marks for his future son-in-law, too. "I am thrilled," he said. "I love Eric. I think he's such a great guy and most importantly he loves Jessica and makes her so happy. As a dad, all you want is for your daughter to be happy and she is. He makes her so happy and I love that. I could not be happier!"
Joe noted that the brood -- which also includes daughter Ashlee Simpson-Wentz, her husband Pete Wentz and their little boy Bronx, 2 -- will spend Christmas together in L.A. "It's all about making a big Christmas for Bronx. Having a baby around at Christmas...that's just magical and it's wonderful. The whole family will be together."
