PGA Tour stars and best friends Cantlay and Xander Schauffele took their better halves on a holiday during the off season to Napa, California last week.
Cantlay and Guidish also announced their engagement.
While there has been plenty of disagreement about all things PGA Tour and LIV Golf by the Tour pros, it would seem like Perez's wife Ashley is ready to now start something of a WAG war.
At least judging by her comment made to Guidish's holiday snap on Instagram.
"Good wine, better company," Guidish captioned her post.
Ashley then replied: "I'm sorry. That doesn't look like fun.... at all."
She then followed her words with a snoozing emoji.
The comment has since been deleted.
According to her Linkedin, Nikki has been working as a Doctor of Pharmacy for just over two years.
Nikki received her doctorate in May 2018 from USF College of Pharmacy, and previously interned at several hospitals, pharmacies, medical centres and clinics. Before that, she attended the University of Central Florida.
She was first seen alongside Cantlay when he won the Memorial Tournament at Jack Nicklaus' Muirfield Village in 2019.
Cantlay has now won eight times on the PGA Tour in total, highlighted by etching his name on the FedEx Cup in 2021.
Nikki's father Jerry Guidish is an amateur golfer and her grandmother Juliann M Guidish won several club championships.
WATCH: Ashley Perez recently went on an epic rant about her husband leaving the PGA Tour to join LIV Golf.
Perez, a three-time winner on the PGA Tour, recently left the circuit to join the Saudi-backed LIV Golf Tour.
Incredibly, Perez has earned more in three LIV Golf events than he did in his 19 starts on the PGA Tour in 2023.
Including three separate team bonuses of $750,000 for being on the winning 4 Aces side with Dustin Johnson, Talor Gooch and Patrick Reed, he has earned £2,655,667 so far.
Perez has failed to pick up a top 10 in any of the individual tournaments, though.
