Brielle, who began dating the Boston Red Sox minor league pitcher earlier this year, took to Instagram Monday to share a sweet selfie of the two.
“We’re a better version of Barbie and Ken,” she captioned the shot.
Kopech, 20, also took to Instagram to share his own picture.
“It’s hard being this good looking but, it helps when your girlfriend is this hot,” he quipped.
“He’s really sweet,” said Brielle, explaining that the two got together after an acquaintance, who also plays baseball, introduced them. Kopech then reached out to her on Twitter, and they began dating shortly after.
“He’s just thoughtful,” she added. “He’s very thoughtful and I’m not used to thoughtfulness – I feel like I’m pretty abrasive sometimes because I’m not used to someone who’s so nice, very relaxed and chill. I’m used to rude people.”

And Mom approves of the athlete, describing him as “talented and “no drama” – in fact, he reminds her of her own hubby Kroy Biermann.
“He’s super nice. He’s like a mini Kroy: blonde, blue-eyed, comes from a very small town in Texas,” said Kim, 38. “[He’s] very humble, easy moving, drives a big old truck, kind of the same [as Kroy]. It’s funny.”
Brielle and Kopech’s relationship comes after the reality star broke up with her ex-boyfriend Slade Osborne in October 2015.
“You wouldn’t appreciate Michael if you didn’t have a little bit of chaos prior,” Kim said.
