"I hope you enjoy this 'slightly deluxe' 'eternal sunshine' ... thank you to my sweet and perfect friend (Troye Sivan) for this gorgeous 'supernatural' remix. I am so thrilled to reunite for this! It is so special and I love (you) so much!" Grande said in an Instagram story.

Sivan expressed his gratitude to be reunited with the singer and said: "Surprise! (Ariana Grande) we are so back ... very honored to be a small part of the gorgeous world you created."

Grande and Sivan first collaborated for “Dance To This” for the latter's album "Bloom" in 2018.

Grande's seventh studio album was released in the Philippines at 1 p.m. and immediately the hastags #eternalsunshine and Ariana Grande took the top spots on the Philippine trends on X, formerly Twitter, with nearly 300,000 tweets.

Many fans observed Grande's reference to her past relationship with real estate agent Dalton Gomez. 

Grande and Gomez started dating in 2020 and got married in 2021 at the singer’s home in Montecito in Southern California.

Several American media outlets earlier said Grande was the one who filed for divorce 2 months after their initial separation was first reported.

Citing a source, People magazine said the split was “kind and patient” and they have both “moved on.”

Following her split with Gomez, Grande was linked to her fellow "Wicked" star Ethan Slater.
