Today (20th August) is Demi Lovato's birthday, and she's ALREADY been celebrating in style! The 'Sorry Not Sorry' singer shared a short video on Instagram, of her celebrating with Ariana Grande, and some of her crew.
According to Demi, Ariana's manager Scooter Braun was meant to be filming the occasion, but forgot to turn the camera on! As such, Demi captioned her video, 'Okay, last one before bed. They literally filmed/sang happy birthday twice and @scooterbraun STILL forgot to press record 😂 @arianagrande’s face is everything and this video is a perfect glimpse of how f**king happy and rad my birthday is this year. So so happy. And I love my new family. Thank you guys, love you 🙏🏼🙌🏼'.
Scooter also shared the same video saying, 'Happy birthday to the amazing @ddlovato and I’m sorry for again missing you blow out the candles because I forgot to turn on my camera the entire song 🤦🏻♂️. But @arianagrande look at me made it all worth it 😂 happy birthday Demi!'
At the end of the video, Ariana makes a funny face as Scooter jokes he forgot to press record AGAIN! The moment was captured on Ariana's Instagram Story. 😂
Demi was in London last night to watch Ariana on tour, she posted a number of videos to her Instagram Stories showing clips from Ari's performance.
Meanwhile, Ariana Grande is continuing her 'Sweetener' tour, and will be performing in Birmingham, Glasgow and Sheffield next month, as well as two more dates in London in October. Tickets for her London shows are available from Aloud.com
