Camila Cabello confirms romance with Shawn Mendes on Instagram

Camila Cabello has confirmed her romance with Shawn Mendes on Instagram.

The 22-year-old singer took to the social media site on Friday (Aug 9) to wish her boyfriend and Señorita collaborator a happy 21st birthday, and also used the sweet moment to declare her "love" for him publicly for the first time.

She wrote alongside a picture of the pair: "Happy birthday to this magic human, I love you!!!! (sic)"

Camila's post also included four love heart emojis, and comes just days after she revealed the In My Blood singer - whom she has been spotted packing on the PDA with in recent weeks - "means a lot" to her.

She said earlier this week: "I've known Shawn for such a long time, and it's so much fun getting to work and do things with somebody who means a lot to you."

But although she's loving spending quality time with her new beau, she "honestly hates" seeing paparazzi snapping photos of the two of them enjoying a romantic kiss, especially when she doesn't know the photos are being taken.

She added: "It makes me insanely uncomfortable to see pictures of me that I didn't know were taken. I honestly hate it. I don't want to live like a celebrity and have to look perfect every time I step out of my house. I ignore it as much as possible.

"If I'm going to look like s**t that day and cameras are in my face, I don't care because I choose being human and normal."

Meanwhile, it was previously claimed the happy couple have "really fallen for each other".

A source said: "Shawn and Camila originally were just enjoying spending time together and having a summer fling. Camila had just got out of a relationship and Shawn was in the middle of a massive tour.
