DONALD TRUMP & HILLARY CLINTON FAMOUS BOOBS AT ROAST STEAL SHOW ... Totally by Accident

While Donald Trump and Hillary Clinton went HAM on each other during the NYC roast/charity dinner ... they were also getting upstaged by a pair of famous boobs that were expertly placed.

The Internet was rightfully distracted by Maria Bartiromo's cleavage, which was in every shot behind the candidates at the Alfred E. Smith Memorial Foundation Dinner. Organizers of the event tell us it was no mistake the FOX Business host was umm ... prominently displayed.

We're told the 70 people on the 5-tier dais were assigned seats to balance out people from politics, media, business and philanthropy. Obviously, Maria checks the media and business boxes.

Despite all visual evidence, we're told she did NOT get the prime seat due to her fame, or her dress. Sooo ... we just got lucky.
