Talk about a blast from the past.

It's hard to believe it's been seven long years since Ariana Grande and Graham Phillips starred alongside each other in the Broadway musical 13. But over the weekend, the pair came together for a "lil 13 reunion."

Held at Red O restaurant off Melrose in Los Angeles, the duo joined another close friend for a tasty meal where we can only assume they reminisced about their younger years.

"They had a wonderful time. Both of them, and their guests, were an absolute delight and stayed late into the night," a source shared with E! News. "They treated everyone amazing!"

Speaking of younger years, fans may not realize that the pair was once a young Hollywood couple who walked red carpets together and provided relationship goals before a hashtag was a thing.

Since then, Graham found even more success on The Good Wife as Alicia Florrick's (Julianna Margulies) son. As for Ariana, you likely hear her powerful singing voice on the radio day after day.ft;">The 23-year-old recently released her latest studio album titled Dangerous Woman that includes hit singles such as "Into You." In fact, the song just became her eighth track to hit 100 million plays on Spotify. Ariana will soon take her musical talents to the stage once again when she stars in NBC's live rendition of Hairspray. Earlier this month, E! News confirmed that the singer has signed on as Tracy Turnblad's perky BFF Penny Pingleton.ft;">"Penny has been a dream role since Hairspray opened on Broadway," she shared on Twitter when the casting was made official. "At 9, I was (and still am) in LOVE w @KerryButlerNyc. Hope to make u proud."

Perhaps Ariana and Graham are still some of the nicest kids in town!
