On the heels of her controversial comments about gay men recently, hotel heiress Paris Hilton has been caught making out with another woman at a nightclub.

According to a report, Hilton's heated encounter at a Las Vegas nightclub made her boyfriend so jealous, he assaulted the other woman's boyfriend and was later arrested for the attack.

Sources told TMZ that an unidentified male called Las Vegas Metro Police and alleged he was punched in the face by Hilton's boyfriend, 21-year-old male model River Viiperi after he caught Hilton making out with his girlfriend.

The man claimed his girlfriend was "making out" with Hilton at XS nightclub inside the Encore Hotel early Monday morning on Oct. 1.

When Viiperi discovered the affair, he allegedly punched the boyfriend in the face at approximately 2:30 am. The assault required the partygoer to seek medical attention.

When local authorities arrived at the hotel, Hilton had already left the premises but Viiperi was arrested for a misdemeanor battery.

A rep for the 31-year-old reality star-turned-dj has not released a statement on the matter.

Hilton recently has made headlines for making, what some perceived to be offensive comments about gay men.

Hilton caught flak from the gay community after a secret recording of the hotel heiress' conversation about gay men was leaked on Sept. 20.

In the audio, Hilton stated she thought gay men were "disgusting" and "the horniest guys in the world."

Hilton made the offensive remarks while sharing a cab ride with a friend, a gay male model, on Sept. 7 in New York City during Fashion Week.

However, it later emerged that Hilton and her friend were in fact talking about a mobile app, which allowed gay men to meet up with each other for sexual trysts. They were at the same time discussing the story of one gay person, known to have HIV, continued to sleep with other homosexuals.

A cab driver secretly recorded their private conversation as they spoke in the back seats.

Hilton's friend, an openly gay male, initiated the conversation about the way gay men meet for random hook-ups through the mobile app Grindr.

"Ewww. Eww. To get f**ked?" Hilton replied. "Gay guys are the horniest people in the world...They're disgusting. Dude, most of them probably have AIDS."

"I would be so scared if I were a gay guy," the 31-year-old added. "You'll like, die of AIDS."

Hiltnon later issued an apology to the gay community:

"I am so sorry and so upset that I caused pain to my gay friends, fans and their families with the comments heard this morning... I cannot put into words how much I wish I could take back every word...HIV/AIDS can hurt anyone, gay and straight, men and women," she added. "It's something I take very seriously and should not have been thrown around in conversation."

Hilton continued on to say, "Gay people are the strongest and most inspiring people I know. Again, I am so sorry from the bottom of my heart and I feel absolutely horrible. I hope that everyone can accept my apology and know that it is not who I am or how I feel in any way."
