The 24-year-old entertainer and the 32-year-old Australian pop star spent their Monday night (August 7) at Verlaine in West Hollywood, Calif.
Not only did the two pose for a super cute photo, but they also showed up in matching outfits!
“When you show up in the same outfit…” Nick wrote on his Instagram story.
He later shared a group photo and added, “Good night with good people.”
Nick and Delta were also spotted spending time together last month as they hit the gym and grabbed a bite to eat at a nearby restaurant.
The duo dated for almost a year back in 2012, when Nick was 19 and Delta was 27.
