Blueface and Soulja Boy have been beefing heavily on social media this week, which started after the two began arguing about who would win in a Verzuz battle. Well, things escalated quickly ... and Blueface made some pretty outlandish comments to Soulja Boy about Jackilyn, which includes, "Because I fucked your baby mama the day before your baby shower." 

Instagram / @souljaboy The docs say Blueface went on to say things like, "Till Soulja get a DNA test that's my child lil bro I'm the daddy now," and "What's old about your baby mama sucking my ****." However ... the docs say Jackilyn and Blueface did have protected sex one time in 2018, but since then there's been no sex of any kind. 

Jackilyn Martinez & Soulja Boy Jackilyn's attorneys say they sent Blueface a cease and desist letter on Tuesday -- demanding he remove all these defamatory statements from social media -- but instead he mocked Jackilyn by posting on IG,

 "Nobody ever said your name ... I don't even know who you are." Jackilyn claims she has been receiving death threats since it became known she sent Blueface a C&D letter. We reached out to a rep for Blueface ... so far, no word back.
