Married Broadway veterans Idina Menzel and Taye Diggs have called off their marriage. Just kidding! The always charming (and still very married) duo did get salty with each other as they teamed up for a performance of "Let's Call The Whole Thing Off" at a December 5 benefit for The Trevor Project. The former Wicked and Rent co-stars added their own twist to the George and Ira Gershwin classic by making the lyrics more personal. Take a look as the pair argue over potatoes and potahtoes below! (Be forewarned: Their language gets a bit crude toward the end.)
