The couple exchanged handwritten wedding vows at Malibu's Calamigos Ranch on Oct. 28

Even before Justin Hartley and Chrishell Stause exchanged handwritten wedding vows at Malibu’s Calamigos Ranch on Oct. 28, feel-good tears were flowing.

Stause, gorgeous in a Monique Lhuillier gown, made her entrance to Beyoncé‘s “XO” and walked down an open-air aisle blanketed with pink and white rose petals. But before reaching the altar, she stopped to embrace Hartley’s 13-year-old daughter, Isabella, who did double-duty as flower girl and ring bearer. “She’s been such an amazing part of our relationship,” the bride, 36, tells PEOPLE.

“It was really sweet and very touching,” says a guest, who got misty-eyed.

The sweet moments didn’t stop there.

When the This Is Us star, 40, handsome in a black Brooks Brothers tux, and Stause read vows, and then kissed under a canopy of trees in front of their 75 guests – including his tight-knit TV family, Mandy Moore, Milo Ventimiglia, Chrissy Metz and Sterling K. Brown — the guest says, “Chrishell was crying and Justin was so moved. … The whole ceremony was so personal and heartfelt.”

“They don’t make them any better than Justin, and I could not be more thrilled to officially be Mrs. Hartley!” Stause tells PEOPLE exclusively in this week’s issue.

Afterwards, the newlyweds and their guests sat down in a “rustic, romantic” outdoor dining area, with chandeliers hanging from trees and pale pink peonies adorning the tables for a meal of roast chicken and prime rib.

“They hand-selected every single piece of tableware,” says planner Niro Luna, who tapped Archive Rentals for wedding décor and Peony & Plum for flowers. “Justin and Chrishell are both fantastic – and extremely in love with each other.”

The couple did their first dance to The Contours’ “Do You Love Me,” and later, Hartley shared a father-daughter dance with Isabella to Taylor Swift’s “The Best Day.”

“The whole wedding was really centered around how Bella and Chrishell are the two women in Justin’s life,” says a friend. “[They] were saying Chrishell was the last puzzle piece for their family to be complete. It was awesome to see how the three of them are such a tight-knit unit.”

Hartley and Stause danced into the night alongside his This Is Us costars, had a blast in the custom photo booth and served up late-night mini-burgers and grilled cheese.

“The wedding exceeded anything I could have ever imagined,” says Stause.
