Whoa!!! Pauly D is kinda looking huge!
Pauly has always been in great shape but now he looks like he's packed on some serious muscle.
During an appearance at the Hard Rock Hotel in Las Vegas last weekend he strutted his ripped muscly body across the red carpet.
People must've taken notice because he began flexing for the cameras!
Yowza! He's certainly been eating his vegetables.
A source close to him said he's been spending a lot of extra time at the gym, saying:
"He's gained 20 pounds of muscle. He is [exercising] nonstop… three times a day sometimes."
It def shows!
Just look at those arms! It's kinda crazy but he's looking almost Ronnie sized.
We like jacked Pauly!
