Ciara & Future Break-Up 'Beef' Intensifies: Viral Michael Jordan GOAT 'Happy Birthday' Shout-Out, 'Who Really Gives A F*ck' Instagram Blast

Apparently, Ciara and ex-fiance Future continue throwing jabs at one another on Instagram. But will the "Body Party" bombshell always come out on top?

The nonstop break-up drama started with CiCi's infamous diss track, "I Bet." The R&B princess slams her baby daddy for "cheating" during their engagement with sloppy "side chicks." Check it out:

Ciara croons:

I bet you start loving me
As soon as I start loving someone else
Somebody better than you
I bet you start needing me
As soon as you see me with someone else
Somebody other than you
And I know that it hurts
You know that it hurts your pride
But you thought the grass was greener on the
Other side
I bet you start loving me
As soon as I start loving someone else
Somebody better than you

So I'm s'posed to believe that it's Felini's
Calling' your phone?
I'm s'posed to believe that they're asking' you
If you're home
I wasn't born yesterday, not me, can't get that
Ova me, not me
I luv you but I won't be a fool for you
That is just something' that I wouldn't do, babe
I mean I would stay if you could tell the truth
But you can't, no matter how much time I ask

So you can keep that bitch ova there giving' me
The ugly stare
The one with the silicone ass, and the Brazilian
Hair?
You ain't gon' respect me no no no till I'm not
There
See, I got you comfortable, now you ain't really
Scared

Future later responded with his own "heartbreak" tune, but with less viral vigor:

But since that wasn't enough, the mixtape master later bashed his ex on Instagram. Basically, Ciara's missing out on the best thing she could ever have:

future: ""How u gone Upgrade a Upgrada #Hendrix."

And the social media taunts simply continued from there.

Following their rather nasty break-up, Ciara ignored her former beau's birthday on November 20 (2014). But she recently wished NBA legend Michael Jordan a very happy b-day, deeming the 52-year-old b-baller the ultimate "GOAT" (aka, "Greatest Of All Time" or "God Of All Things," etc):

ciara: "HBD. #MJ. #GOAT" (February 17).

Meaning, Jordan > Future.

So the "Honest" emcee later posted:

future: "Who Really Gives a F*ck? babeeee Good Mornin Good Mornin $."

Is Future just jealous, or mabe even hurt? Well, hopefully things eventually work out for the sake of the estranged couple's young son.
