The evidence is piling up!
This time the possible couple was spotted getting their flirt on at a Hollywood hotspot in the wee hours of Sunday morning. From what we hear, the two got along famously!
…And then LEFT TOGETHER!
Now we were wondering before if they were making beautiful music together or just making beautiful music together, but something tells us they weren't working on their next single at 2 AM!
More like they were enjoying being single??
