*Following a short-lived reunion, Khloé Kardashian and French Montana are once again officially “done,” a source tells

The two first began dating last spring, keeping the romance under wraps until Kardashian’s 30th birthday when Montana was glued to her side at her belated celebration at Tao Las Vegas.

Over the summer, Kardashian starred in his music video for “Don’t Panic,” and their romance was filmed in front of “Khloe and Kourtney Take the Hamptons” cameras.

Though the pair split in September, there were no hard feelings – Montana just “wasn’t the perfect fit for her,” a source told People.

But then, they reportedly reconciled around his 30th birthday party in Nov.

And now, they are – yet again – done.

For now.
