Some of our favorite Nickelodeon stars had a sensational and slimetastic time at the first ever UK Nickelodeon Slimefest! The extraordinary Kira Kosarin, Isabela Moner, and Jack Griffo had a spectacular time saying hello to Big Ben and they all headed out for a fantastic time at the Nickelodeon UK Slimefest. Kira Kosarin looked so beautiful rocking a blue, white, and black, open-shoulder dress and had a super cute “OMG” clutch with her. Isabela Moner looked stunning wearing a mauve-colored, two piece attire. Jack Griffo looked awesome wearing a lightning bolt shirt and lime green sneakers at the event.

The sensational trio – Kira Kosarin, Isabela Moner and Jack Griffo had a very hectic time in London from doing a lot of press, being on BBC’s Blue Peter, and even taking some time to sight-see.

Kira Kosarin wrote along with a group of photos she shared through her Twitter account, “Thanks for a great time #Slimefest @NickelodeonUK!”

Isabela Moner shared the excellent photo as seen below through her Twitter account.

Jack Griffo shared the awesome video as seen below on his Twitter account.
