Miley Cyrus and Liam Hemsworth Puppy Birthday Party Pictures

Miley Cyrus left Winsor Pilates in West Hollywood yesterday, then hopped into her Mercedes. Across town her boyfriend, Liam Hemsworth, stocked up on dog food and picked up a cozy bed for a lucky pet. Miley surprised Liam with a dog, Ziggy, on his birthday earlier this year. Ziggy seems to fit right in with her pups, Lila and Floyd. Floyd, Miley's miniature Husky, turns 1 next week, and she's already tweeting her excitement about the major milestone. Their canine companions accompany Miley and Liam on walks around her LA neighborhood.

Liam and his box-office smash The Hunger Games will have some competition at the box office this weekend when Miley's comedy LOL debuts in limited release. The pair are also competing in the 2012 PopSugar 100, so be sure to vote for your favorite stars and enter for a chance to win $2,500!
