"My biggest win of the night was actually @lydiahearst saying YES!!!! This ring belonged to her grandmother Catherine Hearst and @patriciahearst has graciously and wonderfully passed it down to me to give to Lydia. IT'S OFFICIAL!!! What an absolutely perfect and amazing night!! I love this woman with all my heart....#YesThisMeansWhatYouThinkItMeans"
