It must be fantastic going out in public and having everyone thinking you're doin' it with your mom.
There's a 22-year-old guy named Jonathan Nguyen in Los Angeles. And he and his mom are going viral . . . because he posted some pictures of them on Instagram, and she looks young enough to be his girlfriend.
And apparently lots of people make that mistake when they're out together.
He says, quote, "My mom is in her 40s. Her secret to not aging is dieting and exercising. She also has a skin care routine that I'm not too aware of."
