On Tuesday, Khloe Kardashian, 30, hinted once again that she isn't over estranged husband Lamar Odom when she posted a photo of her "LO" tattoo (his initials) on Instagram, along with a heart emoji as the caption.

The picture shows Kardashian gripping her Bentley shift knob -- showcasing the tattoo she got right after marrying the former NBA star in 2009.

The picture certainly suggests there's hope for a reconciliation.

The couple officially separated in 2013, but Kardashian has been conflicted on whether she truly wants to end her marriage or not. She has even spoken about her love for Odom and desire to reconcile on "Keeping Up with the Kardashians."

Could the picture have been Kardashian's way of letting Odom know there's still hope for reconciliation? Rumor has it the "Keeping Up with the Kardashians" star freaked out when she learned that Odom was dating his ex-girlfriend, jewelry designer and model Lara Manoukian.

"Lamar's phone has been blowing up with calls, texts and messages from Khloe ever since she heard about him and his ex. She's just not ready to let go," a source told Hollywood Life.

It was previously reported that the 35-year-old former LA Lakers forward grew tired of waiting for Kardashian to reconcile and decided to rekindle his relationship with Manoukian. He reportedly dated Manuoukian for seven years until cheating on her with Kardashian in 2009.

Odom was also dating Oscar nominated actress Taraji P. Hensen in early 2009. He proposed marriage to Hensen one week before he met Kardashian, reports Perez Hilton. Hensen turned him down because she was reportedly scared off by his quickie proposal.

Kardashian and Odom married in 2009 after only one month of dating.

Odom's substance abuse and cheating allegations led to Kardashian filing for divorce in December 2013.

A Los Angeles court recently filed legal documents to dismiss the entire divorce proceedings if Kardashian does not take action by the end of April.
