MILEY Cyrus "can't get enough" of ex-boyfriend Justin Gaston.
The Hannah Montanaactress has left a series of heartfelt messages for her former partner - who she split from in June after about a year of dating - on social networking website Twitter, sparking speculation they may reunite.
She wrote on Wednesday: "I'm in between happy and sad today. I'm happy because I love you. I'm sad because I can't get enough of you."
Earlier this week, the pair both confessed they were struggling to cope with the split by posting their innermost feelings on the Internet.
Underwear model Justin, 21, wrote: "Just recorded a demo... Now I'm sitting on the couch wondering why we as humans try to pretend everything's okay."
