Groups of girls were captured on video throwing punches and tussling on the ground outside the artist's Hidden Hills home as their fellow partygoers watched on.
A man eventually tried to break up one of the scuffles, but the brouhaha continued to rage at the end of the 10-second clip.
Lost Hills police told the Daily News they received "one or two" noise complaints regarding the party but were not aware of any fights. They opted not to visit the rapper's home and say the party ended at around 10:30 p.m.
"He had a party, it ended on its own, and we didn't have to intervene," an officer told The News.
A neighbor, meanwhile, told TMZ they saw paramedics arrive at the party but did not offer any other details.
Drake, 29, was not pictured in the brawl video but was seen overlooking his backyard while hundreds of people partied below in another clip.
