"She's my best friend and she's also my wife... My wife is hot and I'm in love," Lowe wrote in his Patheos blog.
"Everyone who knows Catherine knows that she's sweet, kind, smokin' hot, goofy, caring, and funny. But my love for her grew beyond just those noticeable traits."
The couple "met and fell in love" on The Bachelor's seventeenth season. They got engaged during the show's season finale, which was filmed in November 2012 and aired in March the following year. Lowe and Giudici wed on live television January 26 on ABC.
While on the show, Lowe added, "I was falling in love with the idea of going through life with her. I managed to make it twenty-nine years before ever feeling this way, and then Bam! She had me stuck in her web of love and there was no getting out. For the first time in my life, I wanted to live my life for someone other than myself."
Lowe also explained when he finally figured out Giudici was "the one" for him.
"I guess it was right around the time we took a little trip to Thailand," Lowe wrote in the blog post.
"Sure there were two other girls on the trip, but something was settling in my heart about Catherine and I knew it was there to stay -- I didn't want to say goodbye to her -- ever... Sometimes I just feel like telling people how incredibly grateful I am for God's blessings in my life and Catherine is certainly at the top of that list."
