Joe, 28, posted a photo yesterday with his nieces after all the festivities and he and his nieces clearly make a pretty cute crew. Alena, 4, was dressed as a mouse and Valentina, 1, got in the princess spirit by dressing as Snow White. Alena and Valentina are JoBro Kevin Jonas’ kiddos with his wife, Danielle.

“Great uncle Halloween day with the nieces



?,” he captioned his photo.

During their trick-or-treating adventures, fans couldn’t help but post photos and videos of the adorable uncle and niece outing. As you can see, Joe’s dinosaur costume is quite elaborate, and it doesn’t seem too comfortable to walk in.

And even though Joe was dressed as a prehistoric creature, it didn’t stop fans from crowding around to try and snap a picture with him.
