Hollywood heir Ireland Baldwin has caught herself quite a Trout!

The 18-year-old daughter of Alec Baldwin and Kim Basinger seemed proud to be on the arm of boyfriend Slater Trout as the couple walked their first red carpet together on January 14, attending a Los Angeles gala celebrating the 50th Sports Illustrated Swimsuit Issue.

Ireland wore a black-and-white dress featuring a short hem and a precipitous neckline — with her nearly-platinum hair pulled up, a bright red color on her lips, and strappy pumps on her feet.

Meanwhile, the 6'3" Slater wore a sleek black suit with his chin-length locks slicked back. According to his official website, Slater is a champion stand-up paddle surfer. "I have met some of the coolest people from all walks of life, young and old," he says of riding the waves. "It’s a sport that anyone can gravitate to."

Even though the thought of having the temperamental Alec Baldwin as a father-in-law would make most guys quake in their flip-flops, it seems like Slater is in like Flynn with the 30 Rock actor. Ireland shared an Instagram in July showing the three of them making goofy faces as they jump into water from the deck of a boat.

They're maybe other fish in the sea, but for Ireland, there's only one Tr—um, okay, we'll stop.
