Khloé Kardashian was sporting a major ring last night. But it was not her 9-carat engagement ring
The sparkler was way more miniature disco ball rather than something you'd give your wife-to-be.
The two simply posed for pics before going inside the bash.
They kept to themselves in a private area near the pool and looked very much in love with lots of canoodling and whispering into each others ears.
Though the house was feng shui designed and guests had to check their shoes at the door, Khloé was the exception.
"No one wanted to bother her because she was wearing such fancy boots," said an event source. "She looked so into her man that everyone just wanted to leave her alone."
They didn't even chat with friends Brittny Gastineau and her mom, Lisa.
Khloé didn't drink during the event, and she and Lamar took off after about an hour in the basketball star's Mercedes.
Why the silent treatment from the usually talkative press-friendly Khloé? We'll assume it's because they sold gave the exclusive first interview to celeb tabloid Life & Style.
Hosted by NSF Clothing, the Humane Society of the United States and GQ, the party also attracted Big Love star Ginnifer Goodwin and Sorority Row's Caroline D'Amore.
