A couple of old heads are having some issues.

Naughty By Naughty's Treach jumped on Instagram this Christmas holiday and typed harsh words for Hot 97's Funkmaster Flex.

FUCK MASTER FLEX, STOP CALLING MY BROOKLYN RELATIVES FOR a SIT DOWN AFTER YOU POP SH!T, I AIN'T LOOKING FOR YOU I'M LOOKING @ YOU, Stay out of JERZ & YOU GOOD, SHOUTS TO UNCLE MURDA & BBOD ON THAT HOT NEW SONG YALL JUST DID, & I ain't on the Song Flex so don't Hate NIGGA, MURDA HANG UP ON THE BITCH NEXT TIME BAMMMMM

Their problems seem to stem from Funk Flex not paying proper respect to Outlawz rapper Hussein Fatal after he died in a car crash last year -- which angered Treach.

Judging by Treach's post, the 48-year old Flex has been reaching out to the 46-year olds Treach's family in an attempt to squash beef.

However, Treach isn't having it and has pulled Flex's New Jersey privileges. So far no word from Flex.
