EJ Johnson is that you?!

The "Rich Kids of Beverly Hills" star, and the son of NBA legend Magic Johnson, showed off his stunning weight loss on Wednesday during an appearance on "Good Day New York." Since receiving gastric sleeve surgery in September, the 22-year-old NYU student has lost over 100 pounds.

And on Wednesday morning, showing off his figure in a fishnet shirt.

"I mean, like, literally almost half my size," Johnson said about his incredible weight loss during his appearance on "The Wendy Williams Show" last week. "It's definitely somewhere far over 100 [pounds]."

Doctors removed 80 percent of his stomach during the surgery, making it the size of a banana. In September, Johnson explained to ET that he still has to exercise and eat healthy in order to reach and maintain his weight-loss goals.

"This is not something that you do and then all of a sudden everything is gone and you're skinny and you're a new person," he stressed. "It's definitely a tool and something that you have to work at."
