Bet you wish you were Danny Garcia right now.
The superstar boxer and his smokin' hot baby mama, Erica Mendez, are having the time of their lives out on vacation in Puerto Rico ... dancin' it up and putting it on display for all to enjoy.
And, yeah ... we're enjoying it, alright.
FYI -- Swift and Mendez have been dating for years and have one child together.
But, it was Mom and Dad having all the fun on Wednesday ... showing off some serious moves to "Quiere Beber" by Anuel AA and sippin' on some drinks.
