Chris Martin's daughter Apple paid tribute to the 'coolest dad in the world' as she posted sweet snaps to mark his 49th birthday. 

The model, 21, who is the daughter of Coldplay frontman Chris and actress Gwyneth Paltrow, shared the tribute to her father on social media on Monday. 

Apple was quick to celebrate her dad's birthday with a collection of throwback snaps as she said: 'I love you more than anything.'

Taking to her Instagram Story, Apple shared a photo of herself and Chris while out for a meal, with her father sporting a huge smile, captioned: 'My hero's birthday.'

In a second post, Apple shared an adorable photo of herself and her brother Moses, 19, with their dad when they were children.

'Coolest dad in the world. I love you more than anything,' she captioned the post, which included a more recent photo of Apple, Moses and Chris. 

It comes after Apple made headlines when it was reported she had been expelled from school for bullying.

But last week, Apple hit out at the allegations calling them 'completely untrue' via her Instagram Stories.

Apple re-shared a comment, she wrote, stating that she wanted to share 'just a quick little message from myself'.

'Hi! I didn't wanna respond but this narrative is completely false and has gotten so out of hand,' she explained in a message to an unnamed account.

'I have never been expelled from any school, especially not for bullying anyone.

'I completely understand ppl not liking me and that is okay! The internet is a place where ppl can share their opinions. 

'But this rumor is completely untrue, I am not that type of person and anyone who is close to me knows that ❤️.'

In 2024, Apple faced bullying accusations after a video showed her seemingly attempting to crash a fellow debutante's photo shoot and roll her eyes at her date at the Le Bal des Debutantes in Paris.

Afterwards, a source close to Gwyneth told DailyMail.com that her daughter is a 'girls' girl' not a 'mean girl'.

'Apple's more playful and fun and she's really a total girls' girl,' the source said.

'She would never mean to take the spotlight from anyone, that was not her intention. To characterize her as a mean girl is very untrue.

'She really had such a wonderful evening and I feel bad that this is even taking away from that because it was such an uplifting evening for her and the other girls.'

Apple went viral over footage said to show her making a brazen play for a photographer's attention while another attendee had her photo taken.

Later, Apple was snapped rolling her eyes at her date, Count Leo Cosima Henckel von Donnersmarck. 

But the source insisted to the Daily Mail that Apple had a 'good rapport' with her aristocratic escort.

'They had cameras on them all day long and they were playing around,' they said. 'It was in total jest and once again, not snarky, not anything negative.'
