Ariana Grande addresses new tattoo with not-so-subtle message following speculation about it

Ariana Grande has got fans all flustered after her latest Instagram post, showcasing a new tattoo.

She's no stranger to body art, but fans couldn't help but notice a new addition etched across her collarbone as she performed night one of her Eternal Sunshine tour in London.

The new inking reads 'I do love you' in cursive style writing, in black ink.

Grande,33, shared a whole load of photos to her Instagram, captioned with a tiny heart and an infinity symbol.

It was slide 10 that has got everyone talking though, with a sideways picture of her singing into a microphone with her eyes closed, showing off the new tattoo.

Eagle-eyed fans soon noticed something very exciting though, when they noticed that a certain someone besides Grande had been tagged in the photo.

She had tagged her (it seems, former) ex, Ricky Álvarez, who the 'thank u, next' singer has been rumoured to be dating.

To compound the rumours further, Álvarez left a comment on the post, writing "It starts with you."

Fans also noticed that Alvarez has a tattoo with the same wording in a different font across his chest.

Grande had previously been in a three-year relationship with her Wicked co-star, Ethan Slater, but it was reported to have ended several weeks ago.

Álvarez, 35, previously worked a backup dancer for Grande, and joined her on The Honeymoon Tour back in 2015.

They became an item in 2016, but broke up that same year but remained close friends.

Now, a decade later it seems they've picked up where they left off.

It was reported by Entertainment Tonight that Grande also changed some of the lyrics about Álvarez while performing.

The 'thank u, next' lyric changed from 'wrote some songs about Ricky, now I listen and laugh' to 'we always find our way back'.

Grande also shared some blurry photos of her with a man that appears to be her former ex.

It was also noticed that Álvarez has also been sharing all of Grande's photos onto his Instagram stories.

He was also spotted dancing at her show was in Brooklyn last month.

Fans first noticed them together again in Austin, Texas on June 26.

A source close to the star told PEOPLE “Ricky has always been a friend and confidant” and she added that she 'really trusts him.'

“He has such great, positive energy, makes her laugh, and she enjoys spending time with him,” they added.

“Ariana has always considered Ricky a friend, she’s not held ill will against him," they continued.

The source praised: "Ricky is dependable, trustworthy and very supportive. Ariana feels she can be herself around Ricky.”

“They’re not jumping into anything serious right away, but Ari is happy to have him back in her life,” they finished.

Grande recently announced that she was cancelling a planned theatre role next year, as she takes a step back from the spotlight to spend time focusing on herself.

Her publicist told PEOPLE: "Ariana will be taking a step back from visibility after she completes the Eternal Sunshine Tour.

"She looks forward to finishing the tour and ending it on a high note, both healthily and happily, and then taking a much-deserved break from public-facing work and appearances, which has led to endless, ongoing public scrutiny.

"This tour has been a beautiful experience for her. She loves her fans and has loved every minute of this tour so much."

"She performs a very physical show, and there is a lot of athleticism involved. She performs healthily and successfully at a very high level night after night."
