Miley Cyrus and Liam Hemsworth got in a little beach time while on vacation in Costa Rica with Liam's brother Chris Hemsworth last week. Miley lounged in Liam's arms while wearing a black crop top and silk shorts in the sand. She was also seen walking along the beach and dipping her toes into the surf. Chris joined the young couple on their trip and showed off his muscular physique while taking in the view of the water. The group had plenty to celebrate while in Costa Rica, including Liam's 23rd birthday, which was on Jan. 13, and the fact that he recently wrapped work on Catching Fire. Even though Miley was on vacation, she has been busy asking her fans to vote for her for Maxim's Hot 100. Miley tweeted, "My fans are the bomb diggity. Keep voting," with a link to the online contest.
