this isn't a duet but if puck goes back to his cheating ways i want quinn to sing britney spears womanizer to him and seduce him while full on dancing cause she won't have the baby bump anymore!!!
hmmm,well great question...lol...and I did refresh my brain on some duets and I think that.... "You Don't Bring Me Flowers" by Barbra Streisand&Neil Diamond или they could sing "Dont Go Breaking my Heart" Elton John&Kiki Dee или "I got Ты Babe" Sunny&Cher ...just a few-haha
