Well, the dress has been found ... to be a fake!

He’s just standing there and we already sense the weak knees coming on!
And looking too cool for the step-and-repeat, the 28-year-old rocked an oxblood suede Gucci bomber jacket with an unbuttoned blue shirt and dark jeans.
Rob definitely got away with a casual outfit, especially considering he was also wearing black Adidas sneaks!
Hey, he still looks gorgeous though!
