It seems that Khloe Kardashian is trying to dispel rumors of her being pregnant.

The reality star is reportedly on a very strict diet and exercise routine ever since her split with Lamar Odom and recent break-up with French Montana, Perez Hilton reported.

"Khloe is at rock bottom. Lamar Odom and French Montana both cheated on her and now she's on a self-destructive mission.

"Food has become her enemy. She's constantly at the gym and eats solids only twice a week... She barely eats, but she's drinking almost every night. Champagne, vodka, tequila - doesn't matter what it is, she downs it.

"She doesn't seem to realize that she's not doing her body any favors... She's sabotaging herself and the results could be really bad," the Perez Hilton report quoted an unnamed source as saying. Based on several other reports, the source seems to be Star magazine.

Rumors of Khloe possibly carrying Lamar Odom's baby circulated online after the two were speculated to have been seeing each other again.

Hollywood Life previously reported that according to its source, those close to Khloe think she's finally having the sought-after baby with her estranged husband.

"Khloe's been acting very strange over the past month, refusing alcohol and ditching activities with friends and family because she says she doesn't feel well," Hollywood Life quoted OK magazine as saying.

"Even though she hasn't told anyone that she's pregnant, it's no secret to her loved ones that she's seeing Lamar," the source added, according to Hollywood Life.

It seems the no-alcohol habits of Khloe have changed, after all. And with it, could be the death of those pregnancy rumors.

In addition to a new diet and exercise regimen, KK has also upgraded herself in another way.

Mail Online reported that Khloe is rocking new grillz, as spotted during Kim Kardashian's birthday.

"The 30-year-old flashed a glimpse of her mouth jewels as she smiled through heavily pouting lips on arrival at TAO Nightclub in Las Vegas to celebrate Kim's 34th birthday," said the outlet.

It isn't clear who influenced KK's sudden love for shiny gold grillz - perhaps dustings of ex-boyfriend French Montana?

Nevertheless, Khloe seems to be more confident this time, even posting to Instagram: "The woman who does not require validation from anyone is the most feared individual of the planet."
