French Montana is going viral this morning - for allegedly "feeling up" on Kendall Jenner's leg. The two looked a little too comfortable, as they sat together on the couch at sister Kourtney's 40th birthday party on Thursday night.

French Montana, a rapper originally from New York, used to date Kendall's older sister Khloe. The two were romantically involved for a year, and even discussed marriage.

French and Khloe were a thing back in 2014 and endured a slightly awkward breakup that was covered on Keeping Up With the Kardashians. Flash-forward five years and several dozen Kardashian cheating scandals, and Khloé and French seem to be hanging out with each other again!

But last night, Khloe wasn't the Kardashian sister that French appeared interested in.

Its not clear how Khloe feels about her lil sis canoodling with her ex.

Here are the pics. Look at French touching Khloe's sister's leg.
