Ariana Grande hung out with ex-boyfriend Graham Phillips over the weekend.

Just weeks after reuniting with Big Sean in Los Angeles, the "thank u, next" singer caught up with yet another ex—this time in New York City. The two, who dated from 2008 to 2011 after meeting and starring in the Broadway musical 13, were photographed arriving at Carbone restaurant on Saturday (Mar. 9). So was this reunion a date or simply two friends just catching up? It's unclear for now, but you can see the pics here.

According to E! News, Grande is very much single. "She's seen some of her exes, but she's not dating any of them. She's just catching up with people that she once cared about and had a connection with," an insider shared, adding that her main focus is preparing for her Sweetener Tour, which kicks off next Monday, March 18.

This isn't the first time Grande and Phillips have reunited since their break up, anyway. The pair—who have remained friendly over the years—got together with a few of their 13 castmates in 2016 and then again on Valentine's Day weekend this year. Grande even shared this video of herself singing with Phillips and Elizabeth Gillies on Instagram.

Ps. In case you're wondering where you've seen Phillips lately, he starred in Riverdale's second season, playing Veronica Lodge's villainous ex Nick St. Clair.
