The Pirates draftee opened up on his relationship with the social media superstar in an interview with the Pittsburgh Post-Gazette this week ... saying they both bonded over being so popular that going out in public is a real "pain in the butt."

"If one of us went out in Baton Rouge by ourselves, there’s probably gonna be someone there asking for something -- picture, autograph, whatever," Skenes told the outlet.

As we previously reported, there was a ton of speculation surrounding the couple recently ... especially after Livvy started popping up at his games.

Her appearance at Skenes' Single-A debut in Bradenton on Tuesday resulted in so much commotion, she had to move from her seat behind home plate to the broadcast booth just so she could get some peace.

Skenes -- the top pick in the 2023 MLB Draft -- said despite being able to relate to each other on the hype surrounding them, he wishes people would leave her alone at the ballpark.

"I do wish she could come to a baseball game and just enjoy it," he added. "It does irk me. I don’t have any control over it. She really doesn’t either. I’m sure it’ll get better as I go up levels, but that’s something I want for her."

As for how they met, Skenes said it was a "small-world type of thing" -- his best friend was dating Dunne's roommate and fellow LSU gymnast, Elena Arenas.
