Selena Gomez may hate talking about Justin Bieber when it's inconvenient for her, but she doesn't mind opening up once in a while when it's about the music. The 'Slow Down' songstress revealed that while 'Stars Dance' is her most personal album to date, it was also one of the most difficult to record because it was so close to her heart.

Gomez admitted that 'Forget Forever' and 'Love Will Remember' were excruciating to sing because they're so personal, but that it was ultimately a good experience. She told Saturday Night Online (via Hit Zone Online), "Both of those are really strong tracks and very fun and emotional as well. It was really liberating."

As for the infamous voicemail on 'Love Will Remember,' Gomez admitted to InTouch Weekly that it was the toughest for her to sing -- which says quite a bit -- but she wouldn't divulge any more details about its inspiration ... not that she'd need to, anyway!

"Obviously, 'Love Will Remember' is a personal song to me and I don’t really need to say anything," she said firmly. "I think my fans will get it. I think people will figure it out themselves. I'm sure he'll like it too."

We bet he does!
