The clock stops for no one – not even Khloé Kardashian Odom.
The reality starlet has kept a low profile since her husband Lamar Odom was charged with a DUI in August, but attended a private corporate function for Sears at the Mirage in Las Vegas on Tuesday.
“She’s going through hell in her personal life but that doesn’t mean life stops,” a source tells PEOPLE of Kardashian Odom’s appearance with her sister Kourtney at the scheduled meeting for the department store, which carries their Kardashian Kollection.
Kardashian Odom has also been fulfilling her contractual obligations to film scenes for Keeping Up With the Kardashians while spending time apart from her husband, who had a short rehab stint in early September.
“[Her mom] Kris just wants her to move on with her life,” a Kardashian insider says of Kardashian Odom, who recently removed her married name from her Instagram profile. “Khloé’s not getting through to [Lamar] so what can she do? He is not receptive to her efforts whatsoever. He isn’t responding to anyone.”
Odom will appear in only one episode of the upcoming season of the Kardashian’s E! reality show – which will also feature new mom Kim Kardashian (sans baby North and beau Kanye West) – but Kardashian Odom has filmed without her husband, according to the insider.
“When there’s an extreme personal situation, you take time off,” says the source. “And she’s taken time off but things don’t just wait for her. The show goes on.”
