Rob Gronkowski, Johnny Manziel Gather Bikini-Clad Harem in Vegas

As one of the most notorious partyhounds in recent NFL history (which is TRULY saying something), we all know New England Patriots tight end Rob Gronkowski has never met a rager he couldn’t make his own. 

And from all his myriad appearances at huge sporting events, music festivals and other three-ring-circus-type environments over the past year, we’ve got every reason to believe that new Cleveland Browns quarterback Johnny Manziel may have the party fever to match Gronk molly-girl-for-molly-girl.

Well, if this round of Twitter pics from Las Vegas this weekend (posted to Crave sports site NESN) is any indication, we may be witness to the formation of a true modern-day Justice League of Partying.

Gronkowski and Manziel united their already gargantuan party appetites to take Sin City by storm this weekend, even pulling together as many bikini-clad women as they could find for a hedonistic pic of epic proportions.

And as the scores of pictures at NESN can attest, this was just the tip of the Gronkzel iceberg from this weekend’s festivities.

With Gronkowski still rehabbing from that ACL-MCL-shredding injury suffered last season and Manziel already earmarked for backup duties in Cleveland, you’d think both guys might have some more pigskin-related issues on their minds.

But Vegas is Vegas…party on, bros!
