Gronk Enjoying Memorial Day Weekend in Las Vegas

Rob Gronkowski knows how to kick back for the unofficial start of summer.

The Patriots tight end was spotted in Las Vegas over Memorial Day weekend, letting loose and hanging out with Browns rookie quarterback Johnny Manziel.

That’s Gronk in the white tank top in the middle toward the back of the picture with Johnny Football in the grey T-shirt next to him. They’re flashing a “show me the money sign.’’

Gronkowski has been enjoying what appears to be a typical off-season of extra-curricular activities, including playing an intense game of T-shirt Inception with teammate Julian Edelman, making a cameo in the upcoming “Entrourage’’ movie, and guest starring on “Whose Line Is It Anyway.’’

But judging from some of the pictures coming in from Vegas, Gronk is finding time to fit in the gym, which is good news for Patriots fans.
