Johnny Manziel hit the Hollywood club scene again -- this time, rolling into TWO hot spots on a Monday night ... and sang Scott Disick's praises on the way out.
TMZ Sports has footage of Manziel rolling out of The Nice Guy -- where his voice seemed shot ... but he still mustered up the energy to give a shout-out to Disick.
As we previously reported, Johnny and Scott partied together in Vegas over the weekend ... and apparently, Johnny took a serious liking to the guy.
"The Lord knows what's up!"
We asked Johnny about his football career, but that's when he clammed up.
After The Nice Guy, Johnny moved on to Ace of Diamonds strip club ... where the party train rolled on.
Manziel's been partying for a week straight ... starting in Miami, moving to L.A., to Vegas and now back to Hollywood.
