Khloe Kardashian and French Montana get cosy for his birthday!

Los Angeles - Khloe Kardashian "celebrated life" with French Montana on Sunday night.

The 30-year-old reality star further fuelled speculation she has reunited with the rapper after attending his 30th Birthday Party Powered by CIROC Pineapple in Los Angeles, and gushed about her "baby boy" and the "timeless memories" they have created.

Khloe posted a picture of herself and French on a beach in partial silhouette on Instagram, adding a touching message to the rapper.

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!! ??????

And it seems some of the Keeping Up with the Kardashians star's followers responded badly to the post, as she later criticised people for not appreciating "genuine love".

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!

The posting from Khloe - who split from French in September after seven months of dating - comes a few days after she used social media to reach out to estranged husband Lamar Odom on his 35th birthday.

On Thursday, she posted a picture of a piece entitled Closure which seemed to admit the pair didn't say goodbye when they split.
