WATCH: 'Funcle' Joe Jonas Dances With Niece In Adorable Video

Joe Jonas isn't a regular uncle, he's a cool, fun uncle — a "funcle" some would say — and he proved why he earned that title in an adorable new video with one of his nieces.

The "Work It Out" singer took to his Instagram on Monday (September 23) to share a sweet clip of him having fun with his 7-year-old niece Valentina, the youngest daughter of his older brother Kevin Jonas and his wife Danielle, per People. The heartwarming moment was seemingly captured as the family attended the wedding of Danielle's sister Kathleen Deleasa to Nick Mirchuk last month.

Joe looked dapper in a dark green suit and cream shirt while Valentina wore a white dress and matching shoes as the pair high-fived and danced around as "What This Could Be" played in the background, a track off his upcoming album Music for People Who Believe in Love.

"Just funcle things," he captioned the post, adding a sweet message on the video itself, writing, "My heart is made for moments like these."

In addition to Valentina, Joe is also an uncle to Kevin's oldest daughter Alena, 10, as well as 2-year-old Malti, Nick Jonas' daughter with wife Priyanka Chopra. He is also a dad to two daughters himself, whom he shares with ex-wife Sophie Turner: Willa, 4, and Delphine, 2.
