Johnny Manziel & Bre Tiesi Crush Cabo for Honeymoon

Johnny Manziel and his smokin' hot wife, Bre Tiesi, aren't wasting any time celebrating the ol' ball and chain ... whisking away to Cabo for some married fun in the sun!!

TMZ Sports broke the story ... Johnny and Bre got hitched in a private California ceremony last week -- 1 year after Manziel popped the question.

Word is they might have a proper wedding bash for all the homies later this year ... but first, they're hitting the sweet Mexican sand for their 1st vacay as Mr. and Mrs. Manziel!

As for what they're up to ... it's all pretty cute-sy stuff -- taste-testing some salsa, lounging by the water, even trolling each other on their March Madness allegiances (seems Bre ain't a Texas A&M fan).

Congrats!!
