Khloe Kardashian was all smiles on Labor Day as she celebrated with Katy Perry at the singer's new Hollywood Hills home.
Although Kardashian's troubled husband Lamar Odom did not attend the party, the reality star was still wearing her wedding ring.
Odom was arrested on suspicion of driving under the influence in California on Aug. 30. He is due in court Sept. 27, and has lost his license for one year as a result of refusing chemical testing.
The arrest came just days after rumors surfaced claiming Odom was seriously addicted to drugs. Us Weekly reports that Odom's drug of choice is cocaine, and that "the addiction had taken over their marriage."
The couple was the object of speculation earlier this summer after allegations that Odom had been cheating on Kardashian hit the Internet. Two different women have come forward claiming to have had affairs with Odom. Kris Jenner later told TMZ that they were absolutely not getting divorced.
