Groban will be the porky diva's first new man since splitting from longtime boyfriend Kermit the Frog.

The singer has appeared onscreen with Miss Piggy before - the odd couple shared a few magic moments in the film Muppets Most Wanted, and Groban teamed up with her again for the music video to accompany his Pure Imagination track earlier this year (15).

The new Muppets series, which launches in the U.S. on 22 September (15), also features cameos from Liam Hemsworth, Reese Witherspoon and Imagine Dragons.
