Jeong Seung Bo, known professionally as Dann, is a South Korean singer, dancer, former member of VARSITY (바시티) and current member of THE KINGDOM (더킹덤, formerly known as KINGDOM). He is currently enrolled in the Broadcasting Entertainment program at Global Cyber ​​University.

He moved to Dubai, United Arab Emirates in 2007 and spent 9 years living there because of his father's work. He studied in an international English school and also was able to learn French.

After returning to South Korea, he became a trainee and made his debut in January 2017 (under his real name) as VARSITY's lead vocalist with the digital single, "Round One". As the group had a mix of Chinese and South Korean members, it was originally managed by South Korea's CSO Entertainment (CSO엔터테인먼트; formerly known as Global K Center) and China's In Hi Media Ltd.

In December 2017, the two agencies decided to transfer the group's management to Jungle Entertainment (정글엔터테인먼트) as reports of frictions between the Korean and non-Korean members began to appear.

By July 2018, the agency confirmed the four Chinese members and the one American member had left the group and moved back to China to promote there. The remaining 7 Korean members continued promoting under the VARSITY name, but all the instability caused them to have no activities for nearly a year. The group quietly disbanded in April 2020.

He switched agencies and re-debuted (under the stage name Dann) in February 2021 as KINGDOM's leader, vocalist and rapper with their first EP, "History of Kingdom: Part I. Arthur".

In April 2024, GF Entertainment (GF 엔터테인먼트) announced the group rebranded as THE KINGDOM ahead of their 8th EP, "Realize".

He enlisted for his mandatory military service on September 9, 2025.
