Paris Jackson has a boyfriend -- and he's quite the hottie!

On Saturday morning the only daughter of the late Michael Jackson hit the gym with her beau, and she couldn't stop smiling and giggling as she held hands and hugged her mystery man. The two hopped into her chauffeured Cadillac SUV, but not before he grabbed her spandex-clad tush. Ahh, young love!

The 16-year-old beauty is currently back in Los Angeles after spending the last year and a half at a private boarding school in Utah, and she's been in good spirits every time we've spotted her out and about. We're guessing this guy has something to do with it!
