(For Harry Styles to win, vote here)

Harry Styles was nominated on January 10 this year for the Best Solo Breakout Award at the iHeartRadio Music Awards 2018, but there is one slightly awkward twist.

Two years after One Direction announced their hiatus, the popular British star is also up against his former bandmates, Louis Tomlinson, Niall Horan and Liam Payne for the same award.

The categories and nominees for the award at the March 11 event is completely determined by online voting, which could prove slightly tricky for hardcore One Directioners.

Fans who are torn between having to pick between their favorite boyband members, have the option of voting for Camila Cabello, who is also nominated as the sole female artist in the category.

Styles' is enjoying a hugely successful solo career to-date. The first single taken off his debut album, "Sign of the Times," was released on April 7 in 2017. It reached No. 1 in the UK and No. 4 in the US.  

The British singer-songwriter unveiled his debut solo self-titled album last year on May 12. It debuted atop the UK and US charts. 

The star is currently on a lengthly world tour which began in September 2017 in San Francisco. It will play over 80 concerts through to July 2018 in the Americas, Europe, Asia and Australasia.
