Drake's Memorial Day party Monday turned pretty ugly when fights broke out and cops came.
We're told police got multiple excessive noise complaints from 9 PM to 10:30 PM, when police paid a visit to Drake's Hidden Hills estate. Things were calmer, so cops left.
We're told girls had been arriving literally by the busload all day. It got extremely rowdy as the day went on and we're told several girl fights erupted. A neighbor tells us at one point paramedics showed up but we don't know the circumstances.
