From the amount of records he's sold to the name of his children - Capital takes a look at some of the most asked questions about Summertime Ball star Usher.
The R&B star's full name is Usher Terry Raymond and he was born October 14th 1978 in Dallas, Texas.
The 'Pop Ya Collar' singer made his acting debut on the UPN comedy series Moesha which starred Brandy.
The 'OMG' star has two children, Usher Raymond V, who was born on 26th November 2007, and Naviyd Ely Raymond, who was born on 10th December 2008.
Usher has sold over 20 million records in the US alone and an estimated total of 65 million across the world.
Before he became the superstar we all know and love, the star was part of an R&B group called NuBeginnings back in 1991.
At the age of 13 he competed on the talent tv show Star Search which led to an audition with current The X Factor USA judge L.A. Reid and the singer signed a deal with the music mogul's LaFace Records.
He has won seven of the 17 Grammy Awards he has been nominated for, has 20 Billboard Music Awards to his name as well as two MTV Video Music Awards. Picture: Twitter
Usher's mum Jonnetta Patton managed his singing career from the start right up until 2007, when they parted ways in terms of business so they could focus more on family life.
Aside from a hugely successful music career, the R&B star has shown his credentials on the big screen by appearing in a number of high-profile movies including the 1998 film The Faculty. The star has credits in six motion pictures and 11 guest apperances in a variety of TV shows. The 'Scream' star is currently preparing for a new role in the forthcoming boxing biopic Hands Of Stone where he will play Sugar Ray Leonard.
When he's not making music, performing or acting, Usher keeps himself busy with his own label RBMG - which signed a young Justin Bieber back in 2008. The singer has tried his hand in the restaurant world and is a part owner of NBA basketball team the Cleveland Cavalliers.
