Nicky Hilton Wedding Dress Wardrobe Malfunction PHOTOS: Flashes James Rothschild Underwear

Hollywood socialite Nicky Hilton already experienced two rather embarrassing wardrobe malfunctions earlier this month. But at least the 31-year-old blonde beauty actually wears panties! Well, sometimes...

Over the July Fourth weekend, the stunning model attended the prestigious Versace Show at Paris Fashion Week flaunting a funky, retro-inspired mini-dress:

But the adorable frock was a bit too short, and Hilton managed to flash some major butt cheek:

Rosie Huntington-Whiteley also raised some Red Carpet eyebrows that same day in this sexy-and-sheer attire...

Anyway, Hilton managed to ignore the minor booty mishap, and just a few days later she officially tied the knot with James Rothschild (July 10).

But, oops! She managed to expose her tight-and-toned derriere (again).

The infamous heiress wowed in a gorgeous Valentino dress during the lavish ceremony at London's Kensington Palace. At one point Hilton was all smiles when she lifted up her skirt, giving guests a great view of her garter belt AND white undies! At least this time, the garment covered all of her private lady parts. View a slew of viral snapshots over at RadarOnline.

And right before the event, Hilton's delicate veil got caught underneath the wheel of an arriving Bentley! Thankfully, the beautiful headpiece was evidently not damaged (via E! News).

Meanwhile, Hilton's famous sister Paris happily approved of the courtship:

"I am so happy for my sister because he's an amazing man and he loves her so much," the popular DJ told New You magazine. "He's loyal and loving. I know that they're going to be together forever and make the perfect couple... I have already met his mother and his sister and they're so sweet. [His sister] Kate actually just emailed me last night and sent me this YouTube video of this 3D hologram that a DJ is using in Asia and she's like, 'You need to do this for your live shows.' She's also going to connect me to someone to help make a hologram for my shows. She always has great ideas. She is an awesome sister-in-law."

So despite some silly mishaps, the wedding went off without any huge disasters. Congrats to the happy couple!
