Who has a tiara, lavender gloves, and her very own show?

The Fantastic Miss Piggy Show (1982)

Directed by Jim Henson

Miss Piggy hosts her own variety show, with special guests John Ritter, George Hamilton and Tony Clifton (Andy Kaufman). Under the direction of Kermit the Frog, the Muppets work in the control room and, amidst chaos, manage to keep the show on the air. Throughout the show, a romantic triangle develops among Piggy, Ritter (who is smitten with the pig) and Hamilton (who is deeply uncomfortable with the star's romantic inclinations).
