Khloé Kardashian is at the end of her rope following husband Lamar Odom's arrest in California yesterday on suspicion of driving under the influence.
"She is really hoping this DUI is a wake-up call," an insider tells In Touch.
Khloé has been out of the couple's house all week but is back at home now.
Lamar has also returned to their home, arriving this afternoon in a taxi.

Early Friday morning Lamar was busted by the California Highway Patrol in the San Fernando Valley driving “in a serpentine manner” at speeds of 50 MPH.
The NBA star wasn't able to perform the field sobriety test and he refused the chemical test.
This latest blow to the marriage comes on the heels of allegations that Lamar has been having multiple extramarital affairs.
