Paris and Nicky Hilton attended the star-studded de GRISOGONO bash at Hotel Du Cap-Eden-Roc in Antibes, France last night, and the sexy and stylish sisters looked amazing as they posed for pictures on the red carpet. Fellow guests included Heidi Klum and Adrien Brody, and this is the eleventh consecutive year the jewelry company has held their party at the swanky hotel.

Today Paris had a shoot with famed photographer Ellen Von Unwerth, but she took to her Twitter to set the record straight about the hot man in her photos. "Before any rumors get started ... The guy in my photoshoot with Ellen Von Unwerth today is not a new love interest," she wrote. "Just the model Ellen hired."

Glad we cleared that up ... and now we can't WAIT to see this pics!

Paris and Nicky Hilton strike a pose at Room 101, the "Presidential Suite" inside Swedish House Mafia's Masquerade Motel event in Miami, and based on P's tweets, it sounds like the sisters are having a blast at the Ultra and WMC events.

Yesterday Paris wrote, "So much fun yesterday at The Masquerade Motel! Like my mask & Kitty ears?" The heiress also gave a shout out to Madonna, tweeting, "@Madonna is literally one of the most amazing women on Earth! She just took over #Ultra with @Avicii #TheBoss #Legend! #MyIdol."

But what about Madge's controversial Molly comment? More on that later...

Paris Hilton is off to Florida for concerts and some fun in the sun, and before hopping on the plane this morning, she tweeted, "On my way to Miami with @NickyHilton & @CamRaFace. #GoodTimes ahead ... Ultra & WMC are going to be sick! #YES!" Can't wait for her to post some sexy Twitpics once she lands ... and you know she will!

Paris' pal, DJ Afrojack will be spinning at the Ultra Music Festival on Friday and at Miami hotspot Mansion on Saturday, so we know where to find her!

P.S. That red sweater? Loves it!

It's the perfect outfit for a greeting card shopping spree!

Nicky Hilton stepped out looking fierce in a pair of fabulous grey boots, skintight leather pants, oversized sweater and funky shades as she shopped for stationary in Beverly Hills, on Wednesday afternoon.

The 28-year-old heiress has been enjoying her newly single status since splitting with boyfriend of four years, David Katzenberg, but she doesn't seem anxious to be tied down any time soon.

This is the first time in years that both Nicky and Paris have been single at the same time. Live it up, ladies!

No one knows how to shop like the Hilton sisters!

Paris and Nicky took a stroll together in Beverly Hills ... going in and out of stores and walking out with plenty of pricey purchases.

We're loving Paris' Chanel purse! Nicky was sporting Christian Louboutin wedges and an Ella Moss dress. Fierce!

Who says you have to wear boring footwear when you're just kickin' it with friends?

Millionaires Nicky Hilton and Brandon Davis grabbed lunched together in Beverly Hills.

While Paris' sis opted for cute, animal print flats, Mr. Davis made his way to the restaurant wearing purple kicks. Seems as though he and Scott Disick have similar taste when it comes to loafers.

Shoe styles of the rich and famous!

Dressing for the winter season, yet also accommodating the warm LA weather, Nicky Hilton stepped out in a tank underneath a fur vest (we're sure it's faux!), paired with a long black skirt and a $1,000 Alexander Wang bag, while on a shopping trip in Beverly Hills, Wednesday afternoon.

The fashion designer picked up a few essentials from Barneys, before she hopped a plane to Miami, where she's currently soaking up the sun, before getting ready for her first NYE as a single girl -- she split with ex-beau of more than four years, David Katzenberg, in July.

For the first time in a long time, Paris and Nicky will be ringing in the New Year as single ladies!

Paris Hilton is already back home in Los Angeles, but it looks like she spent plenty of quality time in Aspen with her family this week. Last night the heiress went snowboarding and shopping with siblings Nicky and Barron (c'mon, is there anything else to do there?) and earlier today she jetted back, just in time to finish wrapping her Christmas presents.

"Sad to leave Aspen, but excited to spend Christmas Eve with my grandpa & entire family," she tweeted. "I love the holidays!" Miss P also posted this shot of her "little Jetsetter Tinkerbell" and added, "Can't wait to get home to all my pets!" Aww!
