Paris Hilton must really love her garter belts, because this is the second time she's stepped out in the sexy lingerie this week!

After a long day of working in the recording studio with Flo Rida, Princess P joined sister Nicky and fam for dinner at the Greystone Manor in Beverly Hills, before meeting up with Brandon Davis for an after party in the Hollywood Hills, on Thursday night.

Hilton has recently been putting all of her time and energy into recoding her upcoming album, and with the help of Snoop Dogg and LMFAO, the sexy socialite claims she's created a "whole new genre."

"It's completely different from my last album," Paris revealed. "I'm going with a whole new genre."

She's a little bit naughty, and a little bit nice!

Paris Hilton took the opportunity to sex-up her sweet LBD with some racy garter belt stockings, which she flashed at a gas station while picking up some candy in Beverly Hills, on Tuesday afternoon.

Looking completely healed from her painful root canal procedure which was preformed on Monday, Princess P spent a busy day taking meetings and working in the recording studio!

Hilton Tweeted, "Another day of back to back business meetings. Busy as usual, very productive day. Loving life," before adding, "Back in the studio with @DJAfrojack @AntonyPreston @Shermanology @TauraStinson & @SEBINOOO."

The heiress recently confessed that she'll be collaborating with Snoop Dogg on new tracks for her upcoming album, which is set to debut sometime this year.

Poor Paris ... she's even followed to the dentist! No wonder Princess P seems upset; she just finished getting a root canal!

The heiress donned comfy black and blue sweats for her appointment at the dentist's office in Beverly Hills on Monday, where she had the painful procedure performed, before driving herself back home to rest. Get well soon, Paris!

In other news, Miss Hilton is gearing up to re-launch her music career this year, and she's recording her new album with none other than Snoop Dogg!

The sexy socialite tells Page Six, "I'm doing my new album, and Afrojack is actually executive-producing the entire thing. There are a lot of very cool collaborations on my album. It should be out in the next few months. We just finished doing my single with Lmfao, then I'm recording with Snoop Dogg."

We can't wait to hear your new tracks, Paris!

Katy Perry wasn't the only one at the grand opening of 1 OAK Las Vegas at The Mirage last night -- Paris and Nicky Hilton were also on hand for the evening's festivities, and the ladies looked gorgeous as they posed for pictures outside the brand new hotspot.

We're not sure if Paris and Katy became new BFFs over the course of the night, but after this sweet tweet, it's definitely a possibility! "@KatyPerry looking gorgeous across the room," P gushed. "Love her hair & dress! #Stunning!" Awww!

Earlier in the day Paris spent time shopping with Nicky, and she also went to the Chanel Numeros Prives exhibit at the Wynn. "So many fashionable & interesting art exhibitions," Paris tweeted. "@KarlLagerfeld rocks!"

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!

Paris Hilton and DJ Afrojack (real name: Nick van de Wall) dined at Gyu-Kaku last night, and later the duo headed to the recording studio with several other pals, where they stayed until about 4am. Can't wait to hear P's new music -- she's definitely been slaving away in the studio all week!

Paris Hilton's pal Kobi posted this shot of the heiress slaving away in the studio last night, and it looks like everyone was having a blast working on her new album. Can't wait to hear it!

P tweeted, "Had fun at Sundance, just got back to LA ... Fun magical night in the studio, now time for bed. Sweet dreams everyone. xoxo Paris." Aw, but she didn't get any time to rest in between jetting back from Park City?! She really is the hardest working woman in showbiz!

Paris brought her posse to Sundance and they took over the town!

Ms. Hilton and beau Afrojack "raved" at the Google Music at Tao event Saturday night. Queen P Tweeted: "I've never seen #Sundance rock & rave like they did tonight at @SundanceLive! So fun! @DJAfrojack killed it! As he always does... #YES!"

To which DJ Afrojack responded: "Great night @ Sundance u guys rocked!! Thnx @ParisHilton for coming out with me the last couple of weeks. Greaaat company..."

Lil Jon also kept the DJ and his girl company, along with Paris' brother Barron and his girlfriend, who were part of the party group.

In fact, the heiress has been spending so much partying, it seems she hasn't been able to take in any sports yet. She Tweeted Friday: "Having so much fun at #Sundance! Can't wait to go snowboarding. :D"

But P can claim all the clubbing is actually business -- after all, she's preparing another album! So as she takes in the sights and sounds, she's formulating her new approach to music. Paris recently told MTV: "It's completely different from my last album. I'm going with a whole new genre. I have Afrojack executive-producing the entire album. So we've just been coming up with the most incredible tracks. I was just in the studio with RedFoo the other night, so we're going to be doing my new single with LMFAO."

We can't wait to hear it! Party on, Paris!
