Harry followed Nadine on social media in August 21, 2014. She followed him a few days
later. They were spotted together for the very first time on November 29, 2014, at an Fleetwood Mac concert in LA with Jeff azoff (Harry's manager) and Glenne Christiaansen (Jeff's girlfriend).
They were spotted together out and about in NYC again later. Harry was spotted out and about with Nadine in NYC on December 18, 2014, in which he was wearing her coat and she was wearing his coat. Nadine was also spotted
leaving the residence Harry was staying in the
morning of December 20, 2014.
For her birthday, on January 7, 2015, Harry gave to her birthday balloons and had a lunch with her earlier. Harry's ex Kendall Jenner supposedly dissed Nadine on January 10, 2015. Her sister Khloé Kardashian posted a video of the two of them singing along to CeeLo Green's hit breakup song "F*** You." Based on the "see no evil, hear no evil, speak no evil" caption emojis we're thinking it means that she wants to throw shade — but
isn't going to say bad things about anybody
directly. Kendall even replaces "girl" with "boy"
so it's from her perspective, singing, "I see you driving 'round town/With the boy I love and I'm like/F*** you."
Nadine and Harry's supposedly exes Cara Delevingne and Kendall Jenner attended his 21st birthday party on February 1, 2015. Harry and Nadine were seen together for the last time on February 4, 2015.
The relationship wasn't confirmed by Harry or Nadine, however, many of his fans (and media) thinks they dated for a few months.
On March 10, 2015, Harry and Nadine's supposedly break-up was confirmed.
