Here’s a clear, sourced breakdown of the core facts and the lingering unknowns.

The band’s key data points, drawn from verified sources, are as follows:

Are there 4 Jonas Brothers?

The actual number of brothers in the band

• The Jonas Brothers are a pop‑rock band formed in 2005 and comprise exactly three brothers: Kevin, Joe, and Nick – Encyclopaedia Britannica (academic reference).
• No fourth brother has ever been part of the group. The persistent rumor likely stems from the band’s early Disney Channel appearances where backup dancers or guests were sometimes mistaken for a fourth member.

The implication: The three‑brother lineup is settled. Any claim of a fourth brother is a fan misconception.

What is Nick Jonas’s diagnosis?

Type 1 diabetes explained

• Nick Jonas was diagnosed with type 1 diabetes at age 13 in 2005 – Encyclopaedia Britannica.
• He manages the condition with insulin and has said he did not initially understand the severity of his symptoms – iHeart/Elvis Duran (radio show interview).
• The condition is sometimes referred to as a disability because it requires continuous medical management, though Nick himself has not publicly used that label.

According to Wikipedia (community encyclopedia), Nick has served as a diabetes ambassador with Bayer Diabetes Care since 2008 and has testified in the U.S. Senate on diabetes awareness – Wikipedia.

Why did Priyanka use surrogates?

Reasons for surrogacy for their daughter Malti

• Nick Jonas and Priyanka Chopra welcomed their daughter Malti via surrogacy in 2022 – Encyclopaedia Britannica.
