New York rapper Tekashi 6ix9ine is raising the bar for himself. The hip-hop newcomer has hyped up his new “FeFe” single and promised a Billboard debut.

Tek went to Instagram last night (July 20) to geek out over the song’s inevitable Sunday premiere.

“Yo, I don’t think y’all understand how hard ‘FeFe’ is. This sh*t drops on Sunday. It’s so hard I want to drop this sh*t today. Remind you, I’m in no beef right now. I’m in no beef. I’m into no type of publicity. Watch this sh*t go eight for eight on Billboard – I just want to see what y’all are gonna say. Watch it go Billboard. Watch it go. I’m excited. I can’t wait for y’all to see this sh*t.”

Earlier in the week, reports claimed Tek had a chain customized for his and rumored “FeFe” collaborator Nicki Minaj‘s video.

The NYC rapper just threw down for a “My Little Pony” chain covered in VVS diamonds. The pendant alone cost $45k, while the chain was $50k, but the real eye-catcher is the mane … which came from Tekashi’s own colorful mop. Tekashi even had his hairdresser style it. The owners of SHOP GLD in Miami tell us he ordered it a few weeks ago, but called them Tuesday saying he needed it for the new music video he’s shooting with Nicki Minaj. (TMZ)

This week, speculation has developed about 6ix9ine and Minaj possibly collaborating on a new “FeFe” record.

A few days ago, Tekashi shocked fans by unveiling his expensive af customized pony pendant.

“I haven’t done this in awhile, it’s been a long tour. I’m back in America. Despite all the jail stuff going on, I lost 30 pounds, I feel good. I just got my hair done. I’m still the fastest kid in the world. I got a new piece. Never been done before. My Little Pony with actual f*cking hair. Human hair. We f*cking did it again.”
