Khloe Kardashian appears to be putting on a brave face despite rumours suggesting her marriage may well be heading for divorce, if sources are to be believed.

Kardashian appeared in West Hollywood yesterday, still sporting her wedding ring despite rumours that she may have finally taken a step back from her troubled husband. Kardashian was seen alone, whilst filming scenes for Keeping Up With the Kardashians, shopping in L.A. The reality star strutted past paparazzi and fans waiting outside the family's Dash clothing store, wearing a monochrome outfit and flashing her large diamond wedding band. 

Despite appearances, Kardashian may be undergoing inner turmoil as a source suggests (speaking to Perez Hilton) that "She is still obviously very upset, but life is starting to move on for her and for the rest of the family." This may be the result of her alleged decision to step back from her husband and her refusal to stage any more interventions. On this matter the source said "Khloe gave Lamar an ultimatum: If he didn't get help, she'd end the marriage. So far, he's ignoring her."

Meanwhile, Kardashian may still be hoping Odom will change his ways, possibly why she continues to wear her wedding ring so publically. Nevertheless, the source also believed the 29-year-old is simply "trying to just live her life, even though it's very separate from the life he's living." The source summed up what they perceived as Kardashian's alleged attitude: that she has "pretty much given up trying to save the marriage." However, it seems there may still be some hope for the couple as the source was adamant that neither Kardashian nor Odom were ready to file for divorce yet.

Meanwhile, Kardashian has indirectly commented on her relationship, tweeting to her fans: "I'm forever grateful for your love and support!"

This could be a sign of Kardashian's determination to maintain a happy appearance, as opposed to how she genuinely feels. This is reinforced by the Instagram pictures, Kardashian has been posting recently. Many simply show Kardashian with friends or on selfies, however the few which do not show her face are the ones which may provide an insight into her true thoughts. The picture she posted yesterday reads "She smiles to mask the pain in her heart. She laughs to conceal the tears in her eyes."
