Briana DeJesus from "Teen Mom 3" is showing off the new junk in her trunk, and her supersized rack ... courtesy of Dr. Michael Salzhauer, aka Dr. Miami.
We got the before/after pics from the epic plastic surgery Briana got just over a week ago. She got 3 things done in one fell swoop -- a Brazilian butt lift, new breast implants (from 375cc to 650cc) and a labiaplasty.
The enhancements are obvious, and although we can't show you the hoo-ha work ... we're told all parties involved are happy with the final product.
As we reported, Dr. Miami Snapchatted all his 'Teen Mom' related work -- which earned him a nomination for a Shorty Award for "Snap Chatter of the Year."
What can he say -- the guy does full c-cup work!
