Now this is one epic collaboration.

John Legend, Kermit the Frog, and Miss Piggy, joined Queen Latifah in a performance of the classic song "The Rainbow Connection" on her talk show -- and the video is amazing.

Latifah will interview the megastars on her show Friday to discuss their new film, "Muppets Most Wanted," and their hot, Hollywood romance.

Although the cute couple have been linked together for years, the two still can’t agree on the state of their relationship.

When asked if they’re married or not, Miss Piggy promptly replied "Yes," while Kermit shakes his head quickly answers "No."

Despite any relationship drama, the duo still make sweet, sweet music together though. 

Check out the sneak peek clip from "The Queen Latifah Show" above. The full interview airs tomorrow!
