According to a source, the USC junior is "heartbroken and devastated" that he hurt Miley Cyrus, especially since he's adamant that no funny business happened on spring break.
Miley, on the other hand, isn't too concerned with the 21-year-old at the moment. Instead of wallowing in misery, the singer escaped to SXSW in Austin where she performed with Future and Rae Sremmurd.
