"It's sweet," Giudici noted with a big smile. "We're ready."
Lowe admitted he's "excited, anxious [and] can't wait for Sunday to get here."
The sixteenth-season Dancing with the Stars participant also announced that he was actually the one to choose their song which they will have their first dance to as man and wife. The song will be "One Woman" by the Randy Rogers Band.
During their GMA interview, Giudici wanted to share some details about her wedding dress but made it clear Lowe wants her gown to be a complete surprise.
"He doesn't want to hear," Giudici said, as Lowe put headphones on.
"It's gorgeous... I've always been just like a cute girl just trying to be fun and playful. But this time, I'm really coming out as a woman and I want to wear something very form-fitting and sexy."
The theme will apparently be "an understated sexy."
"We're definitely a fun, whimsical couple [and] there will be elements of that in the wedding, but 'grown sexy,' it's just very romantic and just a sexy day. But yes, there will definitely be fun elements," Giudici explained.
Giudici seemed to have everything under control when planning their wedding. Lowe called her a "task master."
"She had her list of things that she wanted to do and she knocked them out," he noted.
Although Sunday night's event will mark the first live wedding on television in the history of The Bachelorfranchiseand millions of viewers are expected to tune in, Lowe insisted he and his bride-to-be are not remotely phased by it.
"I don't give that really any consideration. I'm just in the day and I'm going to be focused on her and watching her walk down the aisle in her dress. And we're kind of used to the cameras after all this anyways. So honestly, I'm just going to be zeroed in on Catherine," Lowe explained.
As a former The Bachelor star himself, Lowe also gave the eighteenth season's star Juan Pablo Galavis some advice in light of the controversy Galavis had expressed disapproval over the idea of ABC ever having a gay Bachelor on the show. Lowe had previously been scrutinized in the media for being/not being a "born-again virgin" among many other headlines during his time on the reality dating series.
"Hang in there," Lowe suggested to Galavis. "I know what he said was unfortunate and it can be tough and the media can be pretty tough on someone who says comments like that. Just hang in there, be strong and I think he'll get through it."
