Maroney posted a photo to Instagram with a strongly worded caption where she addresses the criticism."I totally understand why people are upset about me 'changing,' I get it.. but if I can promise you one thing, it's that I will never stop changing. Life is all about growing, evolving, and becoming more and more yourself, and these last couple years I've done nothing but that," she wrote in the caption "I've finally gotten myself to the point where I know who I am, and what I want out [of] life, and you can either love me, or hate me for that," she continued.Critics have been so vocal about Maroney's changes that she actually told Cosmopolitan this month that she did not get lip injections. But even if she did, that's her choice.And for the record, Maroney was only 16 years old when she went to the 2012 Olympic games. She's grown up over the past four years — like any young woman transitioning into adulthood.
