Congratulations to the happy couple! Talking Dead's Chris Hardwick just tied the knot with his actress fiancé Lydia Hearst on Saturday. People reports that the couple said their nuptials in a ceremony in Pasadena, Calif., in front of 450 guests.

The bride, 31, wore a custom-designed Christian Siriano gown. Its sweetheart neckline gave way to a sheer overlay that extended to her wrists and plunged at the back in a deep V. The gown's skirt cascaded in sheer layers, brightening into an ombre effect of pink as it approached the floor. Hearst had given fans a sneak peek of her dress on Instagram prior to the big day, captioning the beautiful shot, "I am truly blessed to have you in my life @hardwick. I love you, and I will never stop loving you. I cannot wait to marry you in one week." The 44-year-old stand-up comedian and Nerdist CEO looked dapper in a dark blue custom Prada suit.

Sharing a love for science fiction, the bride and groom's favorite comic book series, Walking Dead, played into the festivities. Florist Mark Held used the graphic novel to inspire his designs made of red roses, Tardis blue hydrangeas, and Vanda orchids. On the eve of the wedding, Hearst took to Instagram to share a zombie-themed comic-filtered photo of her and her husband-to-be. "My love for you will never die @hardwick," the bride cleverly captioned the post.

Hardwick also shared some pre-wedding excitement on social media. He posted a photo of their wedding rehearsal snapped by the bride's mother, Patricia Hearst. "Wedding rehearsal!" he captioned the shot, followed by "#AllTheEmoji."

Just before she said "I do," Hearst told People she expects to be "blissfully happy" after what she says she couldn't have envisioned as "a more perfect wedding day." While the ceremony was picturesque, she confessed that the most important part was the groom. "Everything else is just a bonus, but Chris is the most important person and vital component to me ... This is a celebration of our love and an incredible moment to share with our family and friends."
