The former Eastwick star wed yesterday in front of around 100 guests at a private ceremony in Pacific Palisades, California.
"Guests looked very touched by all the love, and a few tears were even shed," a guest told People. "[Sara] looked stunning and beyond happy."
Rue hosted The CW reality series Shedding for the Wedding, in which several couples compete in losing weight ahead of their impending nuptials.
Following her appearance on the show, the actress lost over 50lbs in preparation for her own wedding, but insisted that she is now happy with her body weight.
Rue first rose to fame on shows like Popular and Less Than Perfect.
