Kylie Jenner prompted rumors of a second pregnancy on Wednesday afternoon after showing off her soft pink and blue nails on social media. The mother-of-one debuted new false nail extensions in shades commonly associated with baby boys and girls with her 130million Instagram followers. Kylie, whose popular Kylie Cosmetics range has helped turn her into the world's youngest billionaire at just 21, captioned the snap: 'Back at it again with nail bae.'
