Now wait a minute... How do you know? There are so many handwriting fonts. This honestly just looks like a handwriting font to me. I would suggest searching the handwriting section for a similar one, or one that you like just as much or more!

The r's and a's look alike, but i believe this is a custom font. As stated above, those are extremely hard to find.

I read somewhere (it was a while ago so I don't have a source) that all of Selena's fonts are customized and will not be released publicly.
For The First album I would suggest Eurofurence Modified (Already Suggested) and for the Second i would suggest Spyroclassic or Syproclassic Modified (Already Suggested).
Hope this helps.
