YFN Lucci and Young Thug have been beefing for some time now and a few days ago YFN took things to another level when he made some serious allegations. According to him, he slept with Jerrika Karlae – Young Thug’s longtime girlfriend, and it’s not the first time he’s said it. Clearly fed up by the allegations, Karlae went onto her Twitter to not only call out Lucci, but his girlfriend too.
