Selena Gomez -- Not Over Justin Bieber ... (Possibly)

Selena Gomez continues to torture Justin Bieber ... that is if you believe her song lyrics are a reflection of real life ... because her new track is about a on-again-off-again relationship she just can't shake. Sound familiar?

As TMZ previously reported ... sources close to JB are adamant he's acting out from heartache over his split with SG -- claiming SHE won't make a clean break and the two are still very much in contact.

So when SG's song "Come & Get It" was released online Saturday -- riddled with lyrics about an addictive love that's not quite over -- it begged the question, is it about JB?

Here are some gems from the song:

You ain’t gotta worry it’s an open invitation
I’ll be sittin’ right here real patient
Can’t stop because I love it, hate the way I love you.
All day all night maybe I’m addicted for life, no lie.

This love ain’t finished yet ...
So baby whenever you’re ready… come and get it.

Ending with ... This love will be the death of me.
