While you're out trick-or-treating, get ready to see a whole lotta Nicki Minaj cruising through the neighborhood.

The "Super Bass" singer's style is the most-searched Halloween costume for 2011, according to Google.

Wigs, weaves, streaks, skirts, bright lipstick and even funky stuffed animals ... anything goes!

A few of the other top costume searches for the year include Charlie Sheen and Captain America.

Talk about "winning" costume selections!

Lucky ladies!

Nicole Richie, Lauren Conrad and Rumer Willis were among the famous faces who attended the Yigal Azrouel Autumn Party fashion show at the London hotel last night, and everyone appeared completely captivated by the designer's latest collection.

Rumer tweeted, "So excited to be at the Yigal Azrouel fashion show supporting The Children's Institute," and LC added, "Just watched the Yigal Azrouel runway show ... Amazing!" Sounds like it was a huge hit!

Kim Kardashian headed to several meetings in Beverly Hills on Thursday, where she adjusted her high-waisted pants (and wore a bun -- again!)

The reality starlet met (above) with reality mega-producer Nigel Lythgoe (American Idol, So You Think You Can Dance), and also took meetings about her new jewelry line!

Kim Tweeted, "Great meetings today! Just approved my new Belle Noel jewelry collection and its sooo fab!!!! Can't wait to do a fun giveaway!"

And while Kim, 31, kept busy, new hubby Kris Humphries, 26, had nights out this week with Jersey Shore's Vinny Guadagnino, 21.

The duo hit STK in Los Angeles on Tuesday -- they first got close after meeting on a plane last week. While Kim slept, they bonded, with Kris Tweeting: "This is the first time I have tweeted while in the air. Kim is knocked out next to me and I'm so bored I need to be entertained! ... Ran into @vinnyguadagnino 2 times one week. Vegas here we come!"

Such nights out are only fueling the fire that Kim and Kris are having marital problems. Reportedly, Kim is sick of Kris' partying (and flirting) and wants him to get to work. But, Kris argues that the NBA lockout is keeping him from being productive and says he's sick of being filmed all the time for Kim's reality show.

They married in August after only about nine months together.

And on Thursday, reports surfaced that the entire relationship might have been simply a casting decision from the start -- one site claims that E! was husband shopping for Kardashian.

Heidi Klum took the podium at last night's TeenNick HALO Awards at the Hollywood Palladium, and the supermodel paired a black and green Versace dress with several bracelets from her Wildlife collection. Who knew simple could be so sexy?

Heidi tweeted a shot of her and host Nick Cannon, who developed the awards show to help others and honor teens who are making a difference in their communities. We love it when celebs use their fame for a good cause!

They may be keeping relatively quiet about their rekindled romance, but it looks like Jessica Biel and Justin Timberlake are still going strong!

The duo attended Neuro's One Night Only BBQ at Southern Hospitality in NYC last night, and they cuddled up to one another as they mingled with Elton John, hubby David Furnish and Neuro owner Diana Jenkins. One Republic performed at the event, and since this is JT's restaurant, we're guessing the group got the VIP treatment as they sipped on cocktails and noshed on appetizers.

Just the other night Justica attended the In Time premiere afterparty in Los Angeles together, and sources at the bash report that the duo were all over each other. Hmm, does this mean they're back together for good?

Olivia Wilde is hot, hilarious (have you read her Twitter?) and definitely one of our fav actresses, but we have to say something about her digging this polka dot dress out of her dirty laundry and wearing it for the second time this week!

The starlet first sported the vintage frock on Sunday when she was running errands, and we caught her in the same outfit when she was out and about in Hollywood on Wednesday afternoon. Olivia stopped by a waxing salon on Melrose, and even after getting some unwanted body hair ripped out, she was sweet enough to smile for our photogs. Aww, all is forgiven!

Courtney Love and Kurt Cobain's only child, Frances Bean, is engaged!

The 19-year old bride-to-be will be walking down the aisle with Rambles band member Isaiah Silva, according to In Touch.

Frances wrote the following on Facebook:

“Getting to spend the rest of my life loving my best friend makes me the luckiest woman in the world.”

A friend of the couple tells the mag, "They are so happy!"

Ah, to be a supermodel.

The gorgeous Rosie Huntington-Whiteley, 24, attended Burberry's launch of new fragrance Burberry event Burberry Body in Beverly HIlls Wednesday night. Rosie is the first face of the scent.

And how does Rosie keep her Burberry Body in shape? She has three personal trainers (yes, three) across the country and cuts carbs.

Guests included Rachel Zoe, Cat Deeley, Kate Bosworth, Glee's Jayme Mays and Solange Knowles.
