Jen waiting for "Captain Underpants" to be called out
and there she comes to the rescue!
Jen also showed us how she danced in the 70s.
and as you can see, some people were crying from laughter, it was hilarious.
Jen was a bit tired after her performances, lol.
Here you can see the backs of unsuspecting Greta and Jen who had some messages placed on them. Greta's message said: "There is no one in the world like me" while Jen's was: "You are never alone and always loved"
