Celebrity guest stars haven't exactly been bringing good things to the group behind Up Late With Miss Piggy, and the appearance of three new ones could spell the biggest trouble yet on The Muppets.

After major drama ensued when both Elizabeth Banks and Josh Groban arrived on the scene, Miss Piggy, Kermit, Gonzo and the rest of the gang will find themselves caught up in a lot more trouble when they get visits from not only Nick Offerman and Christina Applegate, but Liam Hemsworth as well.

When Fozzie follows some advice from Kermit but takes things a step too far, Offerman will step in to help the two before the situation gets out of control for them both and ruins things. Hemsworth however, will prove to be a bigger challenge for Gonzo when he teams up with Pepe and Rizzo to help him with his online dating situation. He will potentially be helpful at first-but when his charm and good looks potentially cause prospective dates for Gonzo to fall for him instead, it could prove to be a problem.

However, the biggest issue could once again come through the official guest for Miss Piggy's show-Applegate. Though things don't begin on a bad note like they did with Banks, they will quickly go south when the actress brings her host a sweet surprise-but it winds up becoming one that doesn't sit well with her.

The Muppets airs Tuesdays at 8 p.m. on ABC.
