In December, Dr. Lilly Jay, who is Ethan's childhood sweetheart, broke her silence on the entire situation and admitted there were "days when I can't escape the promotion of a movie associated with the saddest days of my life."
However, their relationship sparked controversy as both were still legally married at the time - Ethan to Lilly Jay and Ariana to ex-husband Dalton Gomez.
One particular moment confused fans as they saw Ariana and Ethan shake hands before posing for a few photos.
"In the countless hours I spend rocking my son to sleep, pushing his stroller, marvelling at his sweaty little hands grasping a crayon, I work diligently on my private project of accepting the sudden public downfall of my marriage," she penned.
Ariana Grande and her boyfriend Ethan Slater strangely shook hands as they greeted each other at the SAG Awards.
