The 26-year-old general contractor from Florida elaborated, "I mean... that's just where we're at. Our relationship doesn't need to be public. She's good people, she's an amazing person and we're just keeping it friendly."
He later added, "We have a great time together. We hung out a few times, that's all... She's great. We'll leave it at that."
When ET reporter Lauren Zima probed for more and pointed out Tyler could call Gigi funny, accomplished or gorgeous, for example, Tyler slyly noted, "You just said it for me."
Tyler apparently doesn't want the world getting a play-by-play on his love life after having a very public romance -- and breakup -- with The Bachelorette star Hannah Brown, who is now competing on Dancing with the Stars' 28th season.
"I'm at the point where I don't really want to talk about my relationships. I've dated publicly, so I'm trying to date privately," Tyler explained.
"I'm not in love with anybody right now," he clarified. "I'm in love with myself."
Tyler has also been focused on his modeling career in recent weeks, sharing that a big campaign will be coming out in January 2020.
However, Tyler said there are no plans to model with Gigi, 24, any time soon, and he doesn't intend on asking her or her sister Bella Hadid for advice either.
"She's a little bit more big-time than I am," Tyler said with a laugh. "She's pretty good at what she does... [And] I don't really try to talk [about modeling] with them. I just try to enjoy the moment."
