Megan Rapinoe, Alex Morgan, Julie Ertz and the rest of the women's Team USA soccer are on floats and enjoying their World Cup victory parade in NYC ... and it's LIT!!!
The champs were already chugging champagne -- around 9 AM -- getting turnt up while crowds of people cheered them on!
Of course, it's the 4th World Cup victory for Team USA -- but this seems to be the biggest celebration yet ... the ratings for the women's World Cup in the U.S. were the biggest ever!
