We were seeing double in Vegas on Sunday, and it wasn’t because we were taking shots on the Strip.

Mark Wahlberg posted a photo with his son Brendan, 14, at UFC 285 — and the father-son duo looks more like twins! From the raised eyebrows, to the casual closed-mouth smiles, to their hoodie and hat combo, we might just have a young Marky Mark on our hands. Although “Brendy Brend” doesn’t quite have the same ring to it.

“Fight night with this guy❤️,” Wahlberg captioned his Instagram post that got more than 97,000 likes and counting.

Commenters were quick to point out the duo’s resemblence (…and the fact that Kourtney Kardashian and Travis Barker were casually in the background of the photo!).

“Mini U!!👏🏻👏🏻” one commenter said.

“Father like son your son looks like you,” said another.

Wahlberg told Esquire in 2014 that Brendan actually looked a lot like his own father who passed away before meeting his grandson.

“Because Brendan — there were so many things about Brendan that reminded me of my dad. Just the way he looked. He had this bald head. He’d frown and get these crinkles in his forehead.”

We have to imagine Brendan’s siblings look like their grandfather as well, because honestly, Wahlberg looks remarkably like all of his four children. Along with Brendan, the actor shares Ella, 19, Michael, 16, and Grace, 13, with his wife Rhea Durham.

Durham shared a birthday tribute for their oldest son on his 16th birthday, and Michael looks like a true 50/50 split of his parents. Many first born sons are named after their father, and Michael “Mikey” Wahlberg actually is named after his dad in a way. Walhberg told Esquire he chose the name Mike because his dad called him Mike from the time he was seven years old.

“He used to call me ‘Monkey,’ and I started to get really annoyed with it,” Wahlberg recalled. “So I had my first sit-down heart-to-heart with my dad and I said, ‘Dad, I got to talk to you. I don’t like the name Monkey.’ So he’s like, ‘Well, I’m sorry. I won’t ever call you that again. What do you want me to call you?’ And I said, ‘I like the name Mike.’”

It’s not just the sons who take after their father. In a hilarious side-by-side collage with his daughter Grace, we see just how spot on their resemblance is. The two rock shoulder length curls that are tucked behind one ear, sweet smiles, and have the tiniest hint of dimples peeking through.

“They say we look alike? 💕👼” the former rapper captioned his post.

Yes, Mark! You do!

“Twins before I even saw this photo,” one fan said. “She is Markina. 😂”

“🎯🎯❤️” wrote actress Michelle Monaghan.
