InstagramIt seems like somebody has taken a liking to Ireland Baldwin's boyfriend. Namely (and most importantly) dear old Dad.
Yep. Alec Baldwin appears to have welcomed Slater Trout into the famous family, if an Instagram photo that his daughter tweeted on Thursday is any indication.
Captioned "My boys," the shot shows a bikini-clad Ireland jumping off the back of a boat flanked by Slater and her father while on vacation in the Hamptons.
And given the playful facial expressions, it certainly looks like the three were enjoying each other's company.
The 17-year-old model also posted a pic of herself soaking in the sun with Alec's pregnant wife, Hilaria, tweeting, "Our boat face."
A day earlier, Ireland and 18-year-old Slater were spotted strolling hand in hand.
"I really like the Hampton's & Montauk, this place is fun in the summer," Slater recently posted on Twitter.
Especially when you've gotten the stamp of approval from your girlfriend's pop!
