The Kardashian sisters Kim, Khloe and Kourtney are not backing down in their battle with a high-end makeup company named Chroma Makeup, with sources close to the Kardashian sisters saying that they have a secret weapon to guarantee they will prevail in court.

According to reports, the three Kardashian sisters filed requests to trademark the phrases “Kardashian Khroma” and “Khroma Beauty by Kourtney, Kim, and Khloe” earlier this summer.

However, the requests are still pending, but sources connected with the Kardashian family said that they are confident the requests will be approved — because the man behind the competing makeup line with almost the same name (Chroma Makeup) has not filed for any trademarks.

As previous reports have stated, Michael Rey, the co-owner of Chroma Makeup in Beverly Hills, is threatening to file a lawsuit against the Kardashian sisters over the Khroma Beauty makeup line, claiming their makeup products will cheapen the high-end company he’s built over the last 12 years.

Media outlet TMZ was looking up the Kardashian trademarks and came across another makeup company named “Kroma.”

“Kroma” filed for its trademark back in 2010.

The Kardashian sisters Kim and Khloe were involved in a road rage standoff in Los Angeles on Wednesday after another car nearly ran into them – and some parts of the scene were caught on tape.

According to reports, the unknown driver of a silver Mercedes had been driving aggressively, then suddenly cut into the Kardashian sisters’ lane, nearly colliding with their car. The footage starts when Khloe, who was driving, cut the other vehicle off and cornered it on the far right side of the street. The Kardashian sisters then angrily jumped out of their car, with Kim taking pictures of the Mercedes’ license plate. Khloe, meanwhile, attempted to speak with the driver.

According to sources, a woman was driving the Mercedes vehicle with another female situated at the passenger seat. In the backseat, some guy wearing a CBS Sports shirt was filming the entire road rage standoff.

Kim posted about the incident on her Twitter account, along with a photo of the license plate. “This driver tried to hit us and run while video taping it. She works for CBS Sports. Wow drivers beware. (sic)”

A spokeswoman for CBS Sports released a statement about the road rage standoff with the Kardashian sisters, saying, “There is nothing that makes us believe this person works for CBS Sports.” The rep had no further comment.

The Kardashian sisters Kim, Khloe and Kourtney are facing a new $5-million lawsuit over their endorsement of QuickTrim, a diet pill which allegedly is not effective and does not live up to the weight-loss claims of the celebrity sisters.

The class action lawsuit, filed in Manhattan, New York by a group of dissatisfied customers, reads: “In reality, QuickTrim’s main ingredient is a large dose of caffeine, which the FDA [Food and Drug Administration] has determined as not a safe or effective treatment for weight control.” The group also claims they would have not bought the QuickTrim products if they were aware that it contained caffeine, saying that the Kardashian sisters fed lies to the public through commercials, magazines and social media since 2009. One example is when Kim posted on her Twitter page, “Our QuickTrim cleanse will be massive! Khloe has already lost so much weight.” Last June, Kim also tweeted, “Starting QuickTrim today. It’s officially summer. I want to really get in fab shape! Whose with me?”

The federal court filing adds that QuickTrim is “marketed by the defendants as a clinically proven formula that will increase metabolism, curb appetite and promote weight loss”.

The class action lawsuit against the Kardashian sisters also claims that a number of advertisements for the QuickTrim weight-loss pills feature the Kardashian sisters in “in a bikini or other revealing attire”. Included in the lawsuit are the Kardashian sisters, QuickTrim, as well as various companies that sold the said products.
