Lil Nas won't be getting out until at least Monday...

From TMZ

Lil Nas X is still behind bars after his arrest early Thursday morning ... and now we know he's not getting out until at least Monday.

Authorities tell TMZ ... since the "Old Town Road" singer was arrested on suspicion of battery on a police officer, he needs to go before a judge to have his bail set ... and that ain't going to happen until Monday. Seems there are plenty of others in front of him also looking to bail out ... and Nas ain't cuttin' the line.

We're told this particular charge is an automatic appearance ... and he can't be issued a citation and released, like most misdemeanors ... 'cause "cited out" only applies to nonviolent offenses -- and Nas allegedly charged at police.
