Khloe Kardashian is trying to move on with her life despite all the drama surrounding her husband Lamar Odom. She has returned back to work filming episodes of "Keeping Up With the Kardashians" and was spotted jet setting to Las Vegas with her sister Kourtney Kardashian.

Even though out in public she has been putting on a brave face, sources told E! News that she is "very upset" about her marriage troubles. She has been posting subtle hints on her social media accounts about how she is really feeling but might have just dropped the biggest hint of all - by dropping her husband's last name.

According to E! and several other news outlets the reality star no longer goes by Kardashian-Odom on her Instagram account.

"We couldn't help but notice that Khloe dropped Odom from her Instagram bio," Giuliana Rancic said.

It's not clear when Kardashian made the change but her Twitter page still says 'Khloe Kardashian-Odom."

Several sources claim she is desperately trying to move on with her life and is trying to come to terms with the fact that she may not be able to save Odom.

"She is still obviously very upset, but life is starting to move on for her and for the rest of the family," a source said. "No more interventions, no more trying to save him."

She gave Odom an ultimatum and told him that he either needed to get help for his alleged crack cocaine addiction or the marriage was over. TMZ reports that he did check into a rehab but bailed after one day. He then attempted an outpatient drug program but missed his first meeting with the drug counselor.

"It is what it is. She's trying to just live her life, even though it's very separate from the life he's living," the source said.

She isn't ready to legally divorce her husband and is still holding out hope that he will get help. Until he does, however, she doesn't want anything to do with him. According to Hollywood Life, she will be spending her fourth wedding anniversary without Odom.
