Justin Bieber and Selena Gomez hung out in his Calabasas neighborhood on Thursday, and on Friday Biebs Instagrammed this shot of the two hugging and wrote, "Love the way you look at me." If this isn't a sign that the two are back on, we don't know what is! Then again, they're so hot and cold, we can't even keep up with them...

The young stars began dating in 2010 and made their first public appearance in early 2011 at an Oscars bash, but by November of 2012 they had parted ways, citing their busy schedules as the main reason for the breakup. However, less than two months after that, the duo started hanging out again, and they even planned a romantic vacay to Mexico. Of course, that never happened as the lovebirds got into yet another squabble, but in April she flew to Oslo to surprise Justin and he posted a picture of them cuddling. Though that didn't last, there was another shot of the two posted in July, so they can never seem to go more than a few months without hooking back up.

Wonder if Bieber's recent interview with Power 106's Big Boy had anything to do with the two getting back together? The 19-year-old singer introduced his hit song "All That Matters" on the radio show, and he confirmed that it was about Selena. "It was written when I was in a great place in my relationship and at that time she was all that mattered," he said, adding that he was very much in love with her. "[The breakup] affected us, especially when we are in front of so many people -- it's such a public thing -- it's hard for the both of us. But you know, she's a great woman, I love her to this day."

I guess he's finally ready to come and get it! But will 2014 be the year that they stay together?
