Kim Kardashian Rocks A Poison Ivy Costume For Halloween

Watch out Uma Thurman! Kim Kardashian hosted the Midori Melon Green Halloween Party at the Lavo nightclub in New York City on Saturday dressed to kill as Batman villain Poison Ivy!

We think Kim looked fantastic as the temptress, who last brought the dynamic duo to their knees in Batman And Robin, and might even rival supermodel Heidi Klum's costume this year.

Heidi even Tweeted Kim earlier Saturday while she was putting the finishing touches on her makeup for the night.

"@kimkardashian I think I look sexier than you tonight!! ;)" she wrote.

Kim was able to cast her spell on her best friend/PR guru Jonathan Cheban, who dressed as the Caped Crusader's companion, Robin; but husband Kris Humphries was nowhere to be found.

Earlier in the day Kim Tweeted a pair of photos while getting into costume.

Kim Kardashian And Kris Humphries To Divorce After 72 Days Of Marriage

A happy marriage just wasn't in the cards for socialite Kim Kardashian and NBA player Kris Humphries as it appears that their time together is officially coming to an end after a week or so of rumors that the couple was on the rocks.

After a lavish (and lucrative) wedding on August 20th it appears that after less than three months of marriage the couple will divorce.

TMZ.com is reporting that Kim plans to file for divorce this morning; and the story was just confirmed online via Ryan Seacrest's Twitter account.

"Yes @kimkardashian is filing for divorce this morning. I touched base with her, getting a statement in just a few mins," he Tweets.

We're told Kim will cite 'irreconcilable differences' as the reason for the split and that she'll ask for a regular divorce instead of an annulment, which is usually the case for such short marriages.

The couple had a prenup in place, and despite a wedding that cost nearly $10 million the couple raked it in via Kim's wedding special aired on the E! network. Word is they banked close to $20 million for that.

Last week's issue of Us Weekly reported that the couple were "not getting along at all" and that while Kim is hard at work Kris is always out partying since the NBA is currently in a lockout.

Us reports that a friend of Kim's family told them that Kim and Kris had a big fight before Kim's birthday earlier this month and that she told him "he needs to do something productive... He needs to get off is ass, like, yesterday."

Kim was spotted out this weekend at a Halloween party with her friend Jonathan Cheban and Humphries was nowhere to be found. Interestingly enough, Kim dressed as Batman villain Poison Ivy, and Cheban dressed as the Caped Crusader's sidekick Robin - who Poison Ivy enchanted with her magic spells in the film Batman & Robin. Could something be going on there?

Kim and Kris were spotted having dinner early last week and TMZ says they were "looking less than pleased with one another."

Seacrest, who produces Kim's shows on E! also Tweeted something a little peculiar last night when he was going to bed.

"Hitting the sack, up before the sun to wake up hollywood....what will be tomorrows big headline ??"

Sounds like he already knew.

Kris Humphries Telling Friends Kim Kardashian's Butt Is Fake?

This could get ugly: Sources say Kris Humphries is being loose-lipped about the details of his time with Kim Kardashian. The juiciest bits? Kris' disdain for the Kardashian clan, and that Kim's butt is fake!

A friend told the National Enquirer, "Kris told his buddies that it takes a lot of work for Kim to make her bottom look as good as it does. He revealed all her secrets - how she uses 'booty pads,' Spanx and other things to enhance it. When she takes off the Spanx, the pads and everything else, it's not the same.

"He knows what the real thing looks like - because he's recorded it on his cell phone camera! Despite what Kim said on her show, I think she has definitely had fat injections in her butt."

Blanka Camper, Kris' ex-girlfriend, said the basketball player constantly voiced his disdain for all things Kardashian while she was dating him. She told In Touch, "He would call the Kardashians garbage. He would never watch the show with me. He always bad-mouthed it and said it was trashy. He would ask, 'Why are you watching that?'"

He also took digs at the sex tape Kim made with ex-boyfriend Ray J, mentioning it was the only reason she became famous.
