Rob Gronkowski: Someone Say Tacos ... I'm In, Bro!

If 6'6'' 265-pound Rob Gronkowski shows up to your house, you better have plenty of extra taco meat.

Luckily for Jeff Ballard -- former rep for Charlie Sheen, Zac Efron and Johnny Depp -- he was well-stocked when he got a text from a buddy asking if he could bring a "random" +1 to taco night.

Gronk was in town and decided to swing by the Sherman Oaks backyard party with a mutual friend of Ballard's. Rob crushed 15 carne asada and chicken tacos with the works. We're told normal humans only threw down 2 or 3.

Gronk stayed for almost two hours, throwing a football around with the guests and chilling poolside. Most shockingly, we're told Rob rejected Coronas and opted for water.
