In a new interview with The Daily Mail, Tyra Banks revealed it was actually a super tight New Years Eve dress that made her realize it was time to shed some weight! "I had to have two people help me get into the dress, I couldn't zip it up," she said. "I had overindulged over the holidays on all of the great food." Luckily the big dress incident didnt ruin her NYE celebrations! Tyra said she "laughed it off" and decided it was time to start fresh in the new years. The super model also says when she is having a "fat day" she ignores her cellulite and focuses on a positive.
