One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
Mariah Carey knows how to get red-blooded Americans fired up, and it's not just with her vocal cords!
The songstress sizzled like a hamburger on the grill during a pre-taping of the Macy's Fourth of July Fireworks Spectacular in Liberty State Park in NYC on Thursday.
Singing into a fully bedazzled (duh!) microphone, Mariah showed off her ample bosom and skinny midsection in a tight red gown with side cut-outs.
Doesn't her body look AH-Mazing?!
If that doesn't get you feeling patriotic, nothing will!
