Rappers Young Thug and YFN Lucci have reignited their old beef once more after Thug hopped on Instagram live and threatened to "slap" Lucci.

The rappers had previously bumped heads when Lucci slid into Thugger's girlfriend, Jerrika's dm's - but we don't know what set him off this time.

In response to Thugger's threats, Lucci also hopped on live to deliver some harsh words to Thug - with the word "f*ggot" emblazoned across the video for part of his message.

It seems that the beef is escalating and the two are adamant that it's "on sight."
