This Tuesday, the “Waitress” star posted a photo from her gorgeous British Columbia vacation with her hubby-to-be.
“FEELS LIKE I COULD HAVE BEEN INVITED ON THIS BEAUTIFUL TRIP,” Barely Famous reality star, Erin Foster, wrote in the comments section of Katharine’s post.
Witty Katharine, of course, fired back.
“@erinfoster mommy and daddy need alone time,” she wrote along with a laughing emoji, face palm emoji and shrugging emoji.
RadarOnline.com readers know both Katharine, 34, and Erin, 36, have maintained a sense of humor about their otherwise-awkward age parallel, ever since the American Idol alum started dating Erin’s dad, David, 68.
During Katharine and David’s first public outing, Erin even posted a video of the two, writing: “Excited about my new step mom.”
Then, when Katharine and David announced their engagement via Instagram, Erin liked the post and commented: “Mommmyyy.”
It’s unknown if David finds the age humor funny, but his leading ladies have sure bonded over the awkwardness!
Radar readers know David is a father to daughters Erin, Sara, 37, Amy, 45, Jordan, 31 and Allison, 48, and sons Tim, 49, and Greg.
The Canadian musician popped the question this July during a romantic European vacation. And Katharine said “Yes!”
A source even revealed to Radar that the young stunner is more than ready to have children with her man and start their own little family!
