Khloe Kardashian

It seems Khloe Kardashian could be getting out of control as her sister Kim Kardashian has now revealed that Khloe was suffering from a bad hangover during her wedding.

Kim made the announcement during an appearance on Jimmy Kimmel Live.

"Khloe drank a little too much the night before and I had to wake her up. She was laying down and getting her makeup done while she was sleeping, she was so hungover," the 33-year-old said on the show.

While Kim said everyone drank away a bit too much because they were having fun, some reports noted that Kim's alleged fight with brother Rob Kardashian might have exacerbated Khloe's drinking.

As reported earlier, Khloe has been worried about her brother hiding out in his house all day long, and she feels that it could affect his mental health in the long run. The recent episodes of the family's reality show "Keeping Up with the Kardashians" also showed Khloe trying to reach out to Rob.

"He never leaves the house, like ever. He is definitely very depressed, it is sad. I just want him to get better," Khloe told Brandon Jenner in an earlier episode. "I definitely feel guilty and I don't care what anyone says. I was not there to protect Rob, I was not even there to protect myself," she added.

Reportedly, the Kardashian clan is now worried about Khloe. She has been hitting the party scene and the bottle hard ever since she split with husband Lamar Odom.

"She's managing her drinking and heavy workout schedule fine so far, but people on her team want her to quit one or the other, because it can't be healthy for her in the long run," Radar Online quoted a source.

Reports also indicate that Khloe's drinking problem might have increased after her relationship with rapper boyfriend French Montana became strained.

"Khloe has started waking up," an insider told US Weekly, according to Daily Mail, adding that the possibility of Khloe ending her relationship with Montana has made mother Kris Jenner happy.

Reportedly, Jenner never approved of Khloe's relationship with the rapper as she believed the relationship could end only in a heartbreak for Khloe.

"[Kris] thinks [Khloe] needs to be single... [Kris] worries that Khloe just got out of a marriage," the source said.
