Ariana Grande celebrates first Oscar nomination in $7,100 party dress in London with boyfriend Ethan Slater She celebrated her first-ever Oscar nomination in London with her Wicked costar Cynthia Erivo earlier in the day.
It featured a slim, corset-like midriff with striped stitching that emphasized her slim frame and contrasted with the more voluminous short sleeves and long skirt, which reached down to her ankles.
And Ariana Grande turned to her boyfriend Ethan Slater later in the evening when they were seen stepping out in London to continue the celebrations on Thursday.
Earlier in the day she wrote on Instagram that she couldn't stop bawling her eyes out after being nominated for best supporting actress early on Thursday morning, but there was no hint of distress when she and Ethan headed out that night.
They were seen leaving a studio and driving away in a black van.
