Trump Jr. and Guilfoyle shared a kiss at the Montana Republican Party's annual convention in Billings on Friday, June 22, after he gave a speech.
It was the first time the new couple had bussed in public, as the Daily Mail reported, and Trump Jr. even posted a clip of the kiss on his Instagram Live on Saturday evening.
Trump Jr. called out glamorous conservative-leaning "The Five' commentator Guilfoyle for her support at the event to rally GOP senate nominee Matt Rosendale.
"Just as everyone else thanks their significant others I got to thank Kimberly for coming out here," the President's son gushed.
The outdoors enthusiast added, showing how close they've become, "We're going to take her fishing tomorrow then shooting.
"This is a miniature test to see if she really likes it or if she's going to pretend to like it, but either way we're going to have a good time or at least I will," Trump Jr. joked to the crowd.
He and Guilfoyle -- who's previously been married twice, including from 2001-06 to former San Francisco Mayor Gavin Newsom, now running for California Governor --also shared Instagram photos of their outdoor adventure this weekend, smiling arm in arm in their fishing gear.

But that wasn't all in their romantic whirlwind; Trump Jr. also posted an Instagram pic of him and Guilfoyle posing with rocker Bret Michaels at a Poison concert.
He wrote, "Always great catching up with my good friend @bretmichaelsofficial and all the boys from @poison. You can't find a cooler group of guys who love their fans and do so much for our vets. Great show last night on Long Island. #hairmetal #80s #90s #rock."
Guilfoyle looked very sexy in the backstage shot, wearing a red jumpsuit!
Trump Jr. and former model wife Vanessa married in 2005 and have five kids. She filed for divorce amid scandal, as actress Aubrey O'Day alleged she'd had a secret affair with the billionaire's son.
But now, it looks like Trump Jr. and Fox News bombshell Guilfoyle, who has a young son, are inseparable!
