1:19 PM PT -- Tekashi just streamed from in-home incarceration, setting an Instagram Live record with 2 million people tuning in.
6ix9ine trolled off the bat, bumping "Bad Boys" while toying with a pair of handcuffs.
Tekashi got a lot off his plate ... admitting to being a rat and justifying his snitching. He apologized for singing like a canary, questioned the street code and then bragged about his money, bling and music.
So, pretty much the same Tekashi.
12:05 PM PT -- Tekashi is proud of being a snitch ... he just flexed his ankle monitor in his new music video, which dropped following Friday morning's beef with Meek.
The video also has lots of twerking models and a cute pup.
Meek Mill believes there's only one thing Tekashi 6ix9ine should be doing on Instagram Live ... saying sorry for being a snitch and to all the people he harmed along the way.
The hip-hop star slammed his fellow rapper on Twitter Friday morning ... ahead of 69's first live social media appearance since he was released from prison and ordered to home confinement due to COVID-19 concerns.
Mill's suggesting Nip's alleged killer, Eric Holder, had a history of being an informant just like 6ix9ine ... which is why he was on the streets in the first place.
The insinuation's pretty clear -- once a rat, always a rat ... and Meek's not buying into 6ix9ine's act.
Nevertheless, Tekashi's no longer behind bars for his crimes and is hyping up his Instagram Live show ... in typical boastful fashion.
He's also already fired back at Meek, replying ... "Imagine having a new born baby come into the world & be pressed about a Mexican with rainbow hair." As we reported, Meek's GF gave birth to a baby boy on his 33rd bday.
6ix9ine's hours away from going live, and a lot of people will be watching to see what he's gotta say. Ya gotta think Meek will be paying attention too.
