The famous exes caught up at Verlaine in West Hollywood last night, and wore matching denim-on-denim ensembles for the occasion.
Nick shared a photo from their friendly encounter, captioning the Instagram snap: "Good night with good people."
The former couple, who dated for 10 months before splitting in February 2012, have actually been seen hanging out on several occasions this year. In July, they were photographed hitting the gym together in LA, before heading to a restaurant to grab some dinner.
At the time of their split, a rep for Delta said: "Nick and Delta have decided to mutually end their relationship. At this point in time, they are both focused on their careers as they go on different paths. They remain friends and wish each other the best for the future."
Glad to see the adorable duo remain in touch!
