Miley Cyrus just “can’t get enough” of her pedo ex-boyfriend Justin Gaston.

The Hannah Montana actress has sparked concern that she is not over the 21-year-old model after the pair exchanged a series of sickening messages on the social networking website Twitter.

“I am in between happy and sad today. I’m happy because I love you. I’m sad because I can’t get enough of you,” Cyrus wrote in a Tweet Wednesday.

Earlier this week, the pair both confessed they were struggling to cope with their split in June:

“Just recorded a demo.. Now I’m sitting on the couch wondering why we as humans try to pretend everything’s okay when it isn’t.. Just be real (sic),” Justin Tweeted Tuesday.

Miley replied: “Everything IS ok. Honestly. I can’t change you’re mind and your heart no longer belongs to me. Maybe YOU’RE the one pretending you’re fine (sic).”

The 16-year-old star later wrote: “Why do I continue to torture myself? Drifting away to a better place while listening to ‘Comfortable’. This song makes me cry everytime… (sic).”
