During an appearance on "The Jennifer Hudson Show," the 24-year-old "Cookin' with Brooklyn" star opened up about his "throuple" relationship with his wife Nicola Peltz and Selena Gomez.
Calling the "Only Murders in the Building" star a "very sweet girl," Beckham said that he's enjoyed meeting his wife's friends and shared the trio get along swimmingly.
"She says we're a throuple. She's such a sweet girl," he said of Gomez. "I love when my wife makes new friends, especially really great friends. We all get along."
