It seems that things are getting pretty serious between Khloé Kardashian and her new flame French Montana, as the "Keeping up With the Kardashians" star is apparently not letting anyone come in between them -- not even her family.

Us Weekly previously reported that the 29-year-old's sister Kim and stepfather Bruce Jenner are skeptical of the "Ain't Worried About Nothin" hitmaker, assuming that he "is using Khloé for fame." Despite her family's concerns about her latest love interest, Khloé Kardashian was at La Marina bar and lounge in New York City's Inwood area on June 14 to support the Moroccan emcee during his 30-minute performance.

"Khloé and French arrived together on a yacht around 9:30 p.m. They were holding hands and looked happy together," a source revealed to Radar Online before adding that Kardashian "was having a great time. You could tell she really got along with his rapper friends."

Meanwhile, Hollywood Life claimed that the new couple's love life couldn't be stronger. "The sexual connection between Khloé and French Montana is explosive, like fireworks," a source said. "They are both very affectionate and adventuresome with each other. French is out to please in every way possible."

Not only does the pair have a great sexual chemistry, but they also are able to connect spiritually. "It doesn't hurt that they also have a really strong spiritual connection. They talk a lot about their spiritual beliefs and practices and are both very open-minded," the source said. "Their chemistry is off the charts. There's never a dull moment between them."

In addition, Khloé Kardashian and French Montana co-hosted the official after-party for the Much Music Video Awards in Toronto on June 15. "[They] came in with an entourage and Khloé was in front being escorted in with French's hand on her back," an eyewitness said. "They were cozy and laughing together all night, popping bottles and clearly enjoying each other's company."
