The 21-year-old singer took the playful teasing in jest.
Shawn Mendes knows how to take a joke.
Devine shared two pics for his post: one of Cabello kissing a smiling Mendes' cheek, and one of Devine sitting disinterestedly next to his 27-year-old fiancee, Chloe Bridges. In the courtside pics, which were taken at separate basketball games, Cabello and Bridges are similarly dressed in black, while Mendes and Devine are both sporting tan jackets.
"Month 4 of dating vs Year 4. #whoworeitbetter," Devine, 36, quipped in the caption, referencing Mendes and Cabello's lovey-dovey behavior and Devine and Bridges' bored expressions.
Mendes seemed to love the joke, commenting, "Lmfao incredible."
Bridges, who started dating Devine in February 2015, questioned her fiance, writing, "How do I already look like a parent at little league?"
Zoey Deutch and Sarah Hyland both commented "hahahaha" on the post, while Hyland's fiance, Wells Adams, joked, "At least you kept the jacket."
"I’ve known him for such a long time and I don’t know, he just feels like home to me," said Cabello, who also confirmed she's written songs about Mendes. "Yeah, I’m really happy."
