Miley Cyrus went all out for Liam Hemsworth and sister Noah Cyrus's joint birthday party on Friday. Liam rang in his 27th year with an N.W.A.-themed bash complete with giant pizzas, tattoos, and weed goodie bags, courtesy of Snoop Dogg. The party was a star-studded affair that included appearances by Elsa Pataky, Ashley Greene, and Flaming Lips frontman Wayne Coyne. Earlier in the day, Miley gave Liam a special shout-out on Instagram, writing, "Happiest birthday EVER to my favourite being EVER EVER EVER! You have been my best friend since the day we met..... I am beyond lucky to share sooooo many animals with you!!! 🐷🦄🐶😻🐣 I love you @liamhemsworth." All we know is this party is going to be hard to top.
