It's only been one month since Mallory Hagan won the title of Miss America 2013 ... after KILLING IT in the swimsuit competition ... and it appears she's back to eating like a normal human being again.

24-year-old Hagan was spotted rocking a pink bikini in Hawaii yesterday ... still looking incredible ... with a little more to love.   

Sometimes ya just gotta let loose.  

Miss America 2004 Ericka Dunlap is DEMANDING an apology from the beauty pageant organization -- claiming a racist producer moved her from a prime seat during the competition last weekend because she's black ... but the fact is, she was sitting in a no-Miss America zone.

Dunlap -- the first black woman to win Miss Florida in 2003 -- tells TMZ, "I was sitting there on the aisle, and during the first commercial break during top 15 announcement, a producer came up to me and said, 'Get out of that seat. I need the seat. I don’t give a f**k who you are. Get out of the f**king seat.'"

Dunlap says she refused to move because of the producer's tone, telling us, "I was spoken to as if I didn't matter. If I were any other Miss America, I would have never been spoken to like that. But I'm the only black one who comes back."

Dunlap says an assistant producer eventually came over and helped the first producer physically remove her from her seat -- "I was mortified." Dunlap says she was eventually relocated.

Dunlap doesn't plan to sue, but says she's still waiting for the organization or the producer to apologize for the way she was treated.

A rep for the Miss America organization says Dunlap's story is nonsense -- telling us, "During the night of the telecast, Ericka was unhappy with her seat, and she chose to move to a camera blocked seat that was reserved for the parents of our contestants."

The rep adds, "At the top of the show, the stage manager asked her to move to seat the contestant's parents, and she refused to move. She subsequently was offered a better seat, however she refused it. It was strictly a television production issue."

Mary Ann Mobley is famous for being Miss America 1959, married to Gary Collins and co-starring on shows like "Diff'rent Strokes." Guess what she looks like now!
