The 'Hunger Games' star really misses his ex-fiancee, whom he split from in September after three years together, and wants to win her back.
A source told Us Weekly magazine that the former couple secretly met up last month and "talked like they did when they were together."
The insider claimed that the Australian heartthrob, 23, convinced the 'Wrecking Ball' hitmaker, 21, that they needed to talk face to face, adding: "He pushed to get back in touch. He still has feelings. The attraction hasn't gone away."
The duo have reportedly been exchanging "flirty texts" but Miley isn't convinced they should reunite.
The source said: "She's confused about how she feels."
Liam, who enjoyed a brief fling with Mexican actress Eiza Gonzalez the day after he announced his split from Miley, recently admitted he is "extremely happy" for her following the success of her latest album 'Bangerz' and insisted he is still single.
Miley has been linked to several people recently including her music producer Mike WiLL Made It and Rolling Stone photographer Theo Wenner but has been using her new single status to get to know herself better.
She previously said: "I am genuinely happy, finally, with myself. I think it takes you separating yourself from someone else to really be happy with who you are.
"I've never just been able to be alone, and I'm obsessed with being alone and hearing my thoughts. I'm trying to take this alone time - the five minutes I do have a day - to learn as much as I can."
She later added: "This is the best time of my life. I'm not going to look back on it and be like, 'I wish I hadn't been dwelling over a break up,' you know?"
