Ariana Grande Kisses Gal Pal Elizabeth Gillies

Ariana Grande and Elizabeth Gillies have been friends since they co-starred in the musical 13 on Broadway and later Nickelodeon’s Victorious. But we didn’t realize how close they were until Monday, when the longtime pals locked lips in a video posted to the 22-year-old singer’s Instagram.

“My favorite video of all time @lizgillz. (p.s. this was totally posted by accident,” Grande captioned the clip. “I was editing it in Insta to send to her and it posted accidentally but its great so whatever,” the pop star explained further on Twitter.

In the video, Gillies fixes her hair and tells Grande “it has to be pretty,” before counting to three and puckering up. “Ariana and Liz” quickly became a trending topic with tons of fans weighing in. As for the “Sex & Drugs & Rock & Roll” star, she didn’t seem to mind tweeting her bestie, “@ArianaGrande HAHAHA. THAT GEM.”
