Rumors have been swirling that Khloe Kardashian is back together with ex-boyfriend, French Montana, and a picture Khloe uploaded to Instagram for the rapper's birthday.

Since the couple split up in September, they've still been spending a lot of time together, sparking rumors that the relationship isn't really over. Just a few days ago, Montana was spotted with Khloe at her little sister, Kendall Jenner's, birthday party.

Now Billboard is reporting that Khloe and Montana could be back together, after the Kardashian uploaded a photo of the two of them together on Instagram, paired with a sweet message.

The message read, "Happy birthday baby boy! In only a short amount of time we have created timeless memories. Happy birthday to a man who genuinely lives life to its fullest. "What's understood doesn't need to be explained" @frenchmontana I can't wait to celebrate life with you tonight! You deserve it!!"

After her picture sent people in a frenzy, suggesting that the pair were, in fact, back together, Khloe took to her Twitter in what seemed like an attempt to clarify the caption on Instagram. She wrote, "I guess some people don't have genuine love for people anymore. Blows my mind how critical human beings are these days. Love is love!"

About her relationship with Montana, Khloe told E! News that although they were hanging out, the pair didn't want to put a title on anything.
