More than a year into their relationship, Ariana Grande and Ethan Slater continue to say they are “glad.”

A source close to the couple told Us Weekly that things are better than ever between the “inseparable” pair, who are “living in bliss.”

“Ariana and Ethan have written a whole new book together,” the source said, adding that the actors connected on the Wicked set are “still in the honeymoon phase of pure bliss.”

The co-stars have recently been juggling their relationship with the enthusiastic press tour of Wicked, but sources say that the two have only grown closer while promoting the musical, and “their friends are fully supportive of their relationship.”

“Their relationship has only grown stronger during the press tour for ‘Wicked,’ and Ariana is over the moon for Ethan,” the source explains.

“They have a lot in common, which is something Ari never had in her past relationships.”

A second source told Us Weekly that Grande and Slater's relationship is a “new dynamic” for the “We Can't Be Friends (Wait for Your Love)” singer.

“Ariana is in no rush to remarry,” the second insider added. 'She's happy with where she's at and feels like it's a really healthy situation. Ariana used to move really quickly in relationships, but has learned to slow down."

Even if Grande is not ready to walk down the aisle one more time, a second source admits that she and Slater are still taking serious steps in their relationship, and they are “practically living together” in New York and “building a new life together.”

“She has said that she is very happy with her new life.

“She needed a change of scenery after the divorce,” the source added.
