Mark Allan Hoppus (born March 15, 1972) is an American rock musician. He is the bassist and one of the two lead vocalists of the band Blink-182, as well as the bass guitarist and lead vocalist of the band +44. He is a co-founder of both bands. Hoppus currently hosts his own weekly television series, Hoppus on Music that premiered on September 16, 2010 on Fuse]].
Born in Ridgecrest, California, Hoppus spent his childhood moving back and forth between his mother and father's houses, as they divorced when he was in third grade. He became interested in skateboarding and punk rock in junior high, and received a bass guitar from his father at the age of fifteen. He played in various bands until his sister, Anne, introduced him to Tom DeLonge, who she had met while attending Rancho Bernardo High School. Hoppus and Delonge then formed Blink-182, which became one of the most popular bands of the 2000s. Blink-182 disbanded in 2005, leading Hoppus to form the band +44 with fellow Blink-182 member Travis Barker. Blink-182 then announced their reformation in 2009. However, Hoppus states that he does not consider the +44 project to be "done".
