What'd NFL star Danny Amendola get for his 33rd birthday Friday??
NOT A DOPE NEW ROLEX WATCH!!!!!
At least ... not from his ex-GF, Olivia Culpo, anyway -- 'cause the smokin' hot model says she's keepin' the $12,000 ROLEX she presumably bought for her ex-man's big day.
"Looks like this is my present now," she wrote ... "HAPPY BDAY TO ME"
FYI ... Olivia's birthday ain't until May -- so, yeah. SHAAAAAAAAAADE.
As we previously reported ... Danny was spotted on the beach last weekend with a cutie that wasn't Olivia while Culpo was out shooting bikini pics for Sports Illustrated -- and reports say Culpo was so pissed, she broke things off right away.
