They are too cute!

Mariah Carey and Nick Cannon's twins Moroccan and Monroe got in the Halloween spirit last night by dressing up as Superman and Supergirl, and their parents decided to join in on the fun too!

The Grammy winner shared a pic of dem babies with the caption, "Have a super happy Halloween!!!"

Roc and Roe must have exhausted themselves trick-or-treating, because the whole family piled in bed together at the end of the evening.

Cuteness overload!

Even though Karrueche Tran wore a very similar costume the other day, we have to say, Rihanna totally killed it as a living dead lady gangster!

The R&B superstar tweeted the above shots after getting her body painted blue and wrote, "ARLETA ZOMBIE CHOLA PACK!!! .... My chola name was #ShyGirl." A handful of RiRi's friends also dressed up like this, so even if Karrueche was somewhere nearby, we doubt she'd confront Rihanna about her copycat costume.

This is too cute! Britney Spears and her backup dancers got into the Halloween spirit when they got gussied up as Snow White and the seven dwarves and took some fun photos! The pop princess-turned-Disney princess for the day recreated the 1937 classic and tweeted of the fun to her 33.6 million followers. The former Mickey Mouse Club star proved once a Disney girl always a Disney girl!

The 33-year-old and her lovely ladies have been hard at work at a dance studio in Thousand Oaks, Calif. for the past few weeks, prepping for her two-year Planet Hollywood residency which kicks off on Dec. 27, but took a break to have some Halloween fun. Britney is featured in the middle -- and the girls are wearing various knit caps with "Sleepy," "Sneezy," "Grumpy," "Doc," "Bashful," "Happy," "Dopey," and "Sleepy" written on them, surround the superstar ala the iconic Brady Bunch title sequence.

The "Work B*tch" singer has been a busy bee as of late -- she's also finishing up her eighth studio album Britney Jean, which drops Dec. 3.

Hello Dolly!

What break up rumors? Clearly trying to nip the breakup rumors in the bud, LeAnn Rimes posted a pic of herself and hubby Eddie Cibrian in Halloween costumes. Displaying a united front, LeAnn and Eddie were dressed as famous music collaborators Dolly Parton and Kenny Rogers. We think the costumes are fun -- but sorry LeAnn, you ain't no Dolly!

The country singer-turned-reality star posted the pic with the caption, "Happy Halloween and may you all find your 'Islands In The Stream' #Halloween."

Decked out blonde wig, bandana, paisley shirt and dark jeans, the 31-year-old singer posed with her husband of two and a half years, who was outfitted in a plaid shirt, leather vest and sported a wig and beard.

The couple married in a small ceremony in Malibu in 2011 and have just begun filming a reality show which follows their relationship for VH1.

Star magazine recently reported that Eddie is fed up with LeAnn's bossy behavior and are en route for a $50 million divorce. But it looks like the couple are still together -- at least for now.  

Alana "Honey Boo Boo" Thompson and her family dressed as the Kardashians for Halloween, and they definitely did their fellow realty TV family justice with these costumes!

Honey Boo Boo wore a wig and dressed as Kris Jenner, Mama June went as Kim (possibly before she gave birth to daughter Nori) and Sugar Bear dressed as Bruce Jenner. Anna and Jessica dressed as Kourtney and Khloe Kardashian, but it was Lauryn's Scott Disick costume that really knocked it out of the park.

Honey Boo Boo and company tweeted at Kim, Kourt and Khloe, but the Kardashians have yet to let the world know what they think about the TLC stars' looks...

We can't keep up with all her surgeries!

Heidi Montag recently underwent a breast reduction to undo the size F breast implants that she got back in 2010, when she famously got 10 plastic surgery procedures in one day.

"Sometimes when I'm just sitting there, my breasts hurt so bad, I just wanna, like, rip them off. I have a ruptured disc in my neck, the nerves are pinching my spine, and then I'm having severe back problems with my muscles on my right shoulder. And my spine is being pulled forward from the weight of my breasts," she told Entertainment Tonight.

We're not the least bit surprised, considering each of her boobs weighs approximately three pounds!

The former Hills star replaced her former implants with smaller size D ones.

"I do regret getting the implants. I wasn't warned by my doctor at all about back problems, about the repercussions. My new doctor was like, 'You should never have been allowed by the doctor to get implants this big.' I put my security and sexuality in my break size instead of my confidence," she added.

She should serve as a cautionary tale!

Intentionally, of course!

Kelly Osbourne covered herself in fake blood to go dressed as horror queen Carrie to a Halloween party at Bootsy Bellows last night, and the Fashion Police host managed to make an otherwise scary outfit look glamorous!

The engaged starlet brought fiance Matthew Mosshart, who was dressed as a race car driver, as her date. Her man was actually the one who helped her achieve the festive look!

"Soooo excited for tonight's #Halloween costume!!! Getting my fiance to poor a bucket of blood over my head!!!" she tweeted.

Also at the fete was Kelly O's good pal Miley Cyrus, who came in the same Lil' Kim costume she wore the night before.

We wish it was Halloween every day of the year, because the celebs are so creative with their costumes!

He already pushed back one concert last month, and now Kanye West has postponed several more dates for his Yeezus tour after a truck carrying some of his custom stage equipment crashed and damaged the gear.

On Friday, West's record label said the tour would be postponed until the gear can be fixed, meaning at least three concerts will have to be rescheduled.

A rep for Island Def Jam Music Group said in a statement:

"Yesterday, on the road to Vancouver, a truck carrying The Yeezus Tour’s custom-made video truss and 60-ft circular LED screen was in an accident that damaged the gear beyond repair. This gear is central to the staging of The Yeezus Tour, and central to the creative vision put forth by Kanye West and his design team at DONDA. As a result of this event, it is impossible to put on the show and The Yeezus Tour will be postponed until these essential pieces can be reengineered and refabricated."

The rep added that Kanye "will not compromise on bringing the show, as it was originally envisioned and designed, to his fans." Concerts in Vancouver, Denver and Minneapolis will be postponed, and an update on the rest of the scheduled concerts will be made soon.
