.

From the start, they emphasized that they wrote much of their own material, which reflected R&B influences more than mainstream pop roots. He doesn't have any other siblings.

Where did he study? 

The activist, Justin,  studied at the School for Creative and Performing Arts (SCPA) located in Cincinnati.

During his time at SCPA, he came to know about his eventual bandmate Nick Lachey.

He was mayoral for Cincinnati, Ohio, in the year 2005. He also has a brother named Dan Jeffre. Although the album as a whole retained its R&B orientation on some tracks, the overall package emphasized romantic ballads such as the songs "I Do (Cherish You)," "Because of You," and "The Hardest Thing," each of which entered the top ten on the Billboard Hot 100 chart.

They rocked the time even when the boy bands were high at the peak. And most important, you'll discover just what makes these hunks tick. The diverse environment of the school--located in downtown Cincinnati, but drawing its students from around the greater metropolitan area--and its high level of academic achievement--with more than 80 percent of its graduates continuing their studies in college--meant that the members of 98 Degrees had already gained much experience in the entertainment field by the time they were young adults.

Following their high school graduations in the early 1990s, Jeffre attended the University of Cincinnati as a history major, while Nick Lachey enrolled at nearby Miami University in Oxford, Ohio, to study sports medicine.

He is also known as an activist. 

Jeffre is also known as a member of the multi-platinum-selling boy band 98 Degrees.

Is he a 90's kid?

Justin is an early 70's kid. He was born on February 25, 1973, on Mount Clemens, Michigan, United States of America. 

Who are his parents? Emphasizing their smoother vocal harmonies, self-written material, and orientation toward R&B influences, 98 Degrees nevertheless has found the comparisons with other "boy bands" inevitable: each of the groups has used aggressive marketing campaigns, romantic ballads, and appealing--sometimes even innovative--music videos to capture the youth market.

And that was just the beginning. Although critical reaction to the debut of the group was mixed, a Billboard review of their first single noted that their vocal abilities were "several crucial notches above the competition." Sales of their first album, 98 Degrees, were slow, although the Motown re-release of the album six months after its October 1997 debut with the addition of a new track helped to keep the band in the public eye.

He only made up to 5th positioning the election but, he succeeded in dragging people's attention to Cincinnati. The news casts doubt over previous reports about 98 Degrees adding a new member and would consider recording a new album.
