2NE1's Park Bom gained weight?

On March 1st, 2NE1 attended 2009 Cyworld Digital Music Awards event and had their performance. Their performance was great, as they wore fashionable print tees to put on a powerful stage. 2NE1's Park Bom, who is known for her fit body since 2NE1's debut, wore a short mini one-piece dress for their performance. But despite wearing a mini, netizens were instead focused on Park Bom's belly which seemed to have gained some weight. One netizen commented, "Now those are the 'real'�luxury abs." Other netizens also commented things like, "Her self-management is the problem," "With that kind of body, how can she wear that short mini one-piece dress" and "Although they do not have much activities going on right now, they should have still controlled their body weight." To be honest, she did seemed to have gained some weight, but not much. Were the netizens overreacting? What do you guys think? [gallery]
