The Two and a Half Men star beamed and snapped photos as his daughter, Cassandra Estevez, exchanged vows with childhood sweetheart Casey Huffman at Santa Barbara's Bacara Resort and Spa on Sept. 25.
"He was clearly very proud of her," says wedding planner Jill La Fleur of La Fleur Weddings & Events, who created the lavish day inspired by a mix of nature and old Hollywood glamour. "He had a big smile on his face."
The bride, 25, who met Huffman in junior high, walked down the aisle with her dad to the tune of "Flightless Bird" from the Twilight soundtrack, carrying a bouquet of roses and calla lilies.
The couple said their non-denominational vows under a four-post altar made of birch branches and decorated with white organza, florals and crystals.
During the five-course meal, which included filet and shrimp, Sheen toasted his daughter and new son-in-law. "He told her how happy he was for her," says La Fleur, "and then he teased the groom and made everyone laugh."
After the newlyweds cut their four-tiered, red velvet wedding cake, they hit the dance floor to the nine-piece band The James Gang Encore. Before midnight, guests were treated to mini Kobe burgers, quesadillas and s'mores.
"They're so sweet together," La Fleur says about Estevez and Huffman, who are currently on their honeymoon. "They're so comfortable with each other, and very much in love!"
Estevez is Sheen's daughter with high school girlfriend Paula Speert. He also has daughters Sam and Lola with Denise Richards, and twins Bob and Max with estranged wife Brooke Mueller.
