At bootcamp, Niall sang "Champagne Supernova", but failed to qualify for the "Boys" category.
After a suggestion from guest judge Nicole Scherzinger, Niall was put into a group with four other boys, who also failed to move on in the competition.
He began dating Holly in 2009 and broke up in 2010. In late 2013, he dated the famous British TV personality, Louise Thompson.
After that, he dated Barbara Palvin, a model until 2014.
Simon voted to let him through, Cheryl said no, and Louis quickly added in his yes, and left Niall's fate up to Katy.
He has been in a number of relationships in his life.
While he was emerging as a singer, he was in a relationship with Holly Scally.
I only put the relationships I counted as significant.
This was judged based on number of articles, longevity, spread of coverage, suspiciousness and likelihood of promo ties, and out of the blue factor. There were quite a few more people who were obviously never meant as serious speculation or only had 1-2 articles written about them.* indicates the relationships I think most of the fandom/Niall stans consider to have been real relationships.
