Jwoww was upstaged on the red carpet ... by her own cleavage!

The "Jersey Shore" star showed up to the joint premiere of "All My Children" and "One Life To Live" on Tuesday night in NYC, where she had a wardrobe malfunction on her way to the event.

"Not even at the premiere yet and my Boob already popped outta my dress #bigboobproblems #OLTL," the reality star tweeted from the car.

Luckily for her, she was able to keep her cleavage contained.

Jwoww was at the event to promote her guest starring role on "One Life to Live," which will debut on Hulu and iTunes on April 29.
