Noah Cyrus' attempts to "go to bed early" did not come to fruition last night. The 20-year-old singer and sister to Miley Cyrus was lifting up her shirt for a late-night twerk at 2.36 a.m. on Sunday night – technically Monday morning – with the "July" songstress back on the 'Gram for her signature sexy vibes. Noah, followed by 5.9 million, posted stories showing late-night dancing with a girlfriend, and she even made it a twinning and no-pants deal via fun, Scooby-Doo t-shirts. Check it out below.
