Miley Cyrus and Liam Hemsworth went out on Tuesday night to a Hollywood nightclub for Noah Cyrus's 13th birthday.

They arrived at Level 3 Nightclub and Miley sported a black leather coat and multicolored, floral print pants, paired with gold hoop earrings. Hemsworth donned an unshaved face and a striped shirt, black pants and a jean jacket. The birthday girl, who turned one year older on Jan. 8,  wore a short mini skirt and a red leather jacket while clutching a British flag bag.

The British flag might be a nod to Noah's favorite U.K. band One Direction. Following news of Harry Styles' split from songstress Taylor Swift, Noah posted on Twitter on Jan. 7, "Happy bday to me happy bday to me Harry broke up with Taylor happy bday to me." 

While having some fun with her younger sister on Tuesday before heading to the club, Miley took pictures, and later posted them on Twitter of her cuddling and air-kissing the One Direction singer - his cut-out version that is.

The sisters poked fun at the Noah's love of Styles by posing with a cardboard cut-out of the U.K. singer. In one image, Noah and Miley are in bed with the cutout in between them, as they both blow kissing to Styles. In another image, Cyrus hugs Styles alone in bed with her eyes closed. 

Miley also posted a picture of a figurine Noah has of Styles along with the caption "This might be the creepiest thing I've ever seen."

Noah reportedly begged Miley to get One Direction to perform at her birthday party, according to Cambio, but instead, the boy band 24/7 took to the stage on Tuesday night. Noah did not seem upset about the band playing - she tweeted on the night of her party, "I HVE THE 24-7 INFECTION."
