Ever since Deena Nicole slimmed down, she’s been wearing sexier clothes and showing off her goods, and she took it to the next level at a surprising place — her friend’s wedding!

While rockin’ a strapless red bridesmaid gown, the Jersey Shore  guidette Instagrammed a selfie yesterday, showing off ample cleavage and cheesin’ for the camera.

Now we aren’t here to judge her, but we’re a little worried she upstaged the bride with this sexy look! With smoky, shimmering eye makeup (with lots of eyeliner and mascara, natch) and a tousled waves ‘do, she looks ready for a hot night on the town — not a wedding!

But we think she looks gorgeous regardless. What do you think of her major cleavage? Is it hot or not? Vote below!
