Khloé Kardashian may be letting go of her estranged husband Lamar Odom, but is she shacking up with another ex of hers?

The "Keeping Up with the Kardashians" star was spotted Sunday night leaving Hyde nightclub in Hollywood with French Montana, the rapper the reality star dated after she broke things off with Odom.

This was not the first time Kardashian and Montana were seen out together since they officially ended things in 2015 - the former couple was also spotted dining together at BOA Steakhouse in early February. Plenty of laughs were shared between them that night and, even though a romantic relationship between the two did not work out, they remain close friends in spite of their breakup.

Kardashian's most recent outing with Montana came just hours after she posted a number cryptic, but lengthy Instagram posts about unrequited love and "letting go." The 31-year-old never specifically mentioned Odom in the messages, but strongly hinted she was finally ready to give up on her relationship with her estranged husband, who was found unconscious in a Nevada brothel last October due to a lethal cocktail of drugs and alcohol.

"Letting go with love takes great strength," Kardashian said Sunday. "We have to learn to stop taking on people's problems as if they are our own. Loving people does not mean we have to carry their burdens and confusions on our back."

She continued: "I do believe timing is everything. You forcing your beliefs and dreams down one's throat is only going to cause resentment and possibly manifest deeper issues. Possibly to the point of no return.... Stop shattering your own heart by trying to make a relationship (friend, family, partner) work that clearly isn't mean to work."

Kardashian then went on to address unrequited love.

"You can't love someone into loving you (God I wish it were that easy)," she wrote. "You have to understand... some things ARE supposed to happen in your life, but they just are NOT meant to be."

Kardashian and Odom were married in 2009, but the reality star filed for divorce after it was revealed Odom cheated on her multiple times and had a secret drug problem. After the former NBA player had his overdose scare, Kardashian stopped the divorce proceedings so she could make medical decisions for him while he was in a coma.
