We all know Canelo Alvarez can dance in the boxing ring ... but did you know he's also got the moves outside of it?!?
It's true ... the champ just posted a clip of him shakin' his tailfeather on a boat trip with his new wife -- and his moves ain't half bad!!
The newly weds were enjoying the married life Thursday off the shores of Croatia -- when Canelo began breaking it down for his love, Fernanda Gomez.
There was some kickin', some swayin', some hip movements -- and it was HILARIOUS!
