Things are definitely heating up between Hilary Duff [1] and her new boyfriend, singer Matthew Koma. The two, who were first linked back in January, jetted off to Costa Rica this week for a relaxing getaway. They were spotted showing all sorts of sexy PDA on Wednesday as they lounged on the beach and took a dip in the ocean. Matthew, who attended a SAG Awards preparty with Hilary [2] at the end of January, gave her a sweet kiss before carrying her above the waves. Hilary also showed off her rock-hard abs [3] in a white bikini, while Matthew wore black swimming trunks. The pair's happy vacation is a far cry from what Hilary's ex-husband, Mike Comrie, is dealing with in LA. The former NHL player, who shares son Luca with Hilary [4], is currently under investigation for alleged sexual battery [5]. Hilary and Mike announced their split in January 2014 and finalized their divorce in February 2016.
