'I literally haven't done anything to my face!' Olympic gymnast McKayla Maroney, 20, slams claims she has had lip injections, as she insists her plump pout is from LINER

McKayla Maroney has slammed rumors that she has had lip injections or any other cosmetic procedure after her fans took to Twitter to comment on the plump pout she was sporting during her cameo on last week's telecasts of the US Women's Gymnastics Olympic Trials.

Although it has been four years since the 20-year-old helped the US gymnastics team take home the gold at the London 2012 Olympics, fans were still shocked to see how how much the star's trademark smirk has changed. However, McKayla insists her new look is the result of the make-up tricks she has incorporated into her beauty routine. 

'First of all, that I haven't,' she told Seventeen.com about the rumors that she's had lip injections. 'And I've posted a picture on Instagram last night that was like, how do I make my face look like I didn't do anything to my face when I literally have not done anything to my face?'
