Miley Cyrus & Liam Hemsworth: Kissing in the Car!

Miley Cyrus and Liam Hemsworth are apparently still back on!

The Last Song co-stars — and on-again couple — were spotted making out in her parked car, a Mercedes Benz SUV, on Monday morning (September 13) in Los Angeles.

Miley, 17, and Liam, 20, were seen making out for about 10-15 minutes. Looks like they had a bit of trouble saying goodbye to one another!

Over the weekend, the couple was spotted getting their caffeine fix together. Pictures at JustJaredJr.com!
