Ariana Grande celebrated her 23rd birthday over the weekend, and just threw a party with a bunch of her closest friends! The starlet's Victorious co-stars Daniella Monet, Avan Jogia, Matt Bennett, and Leon Thomas attended the celebration, so there was a mini-Nickelodeon reunion. Don't you love how close they still are?

Obviously, her mom Joan Grande and grandmother Nonna Grande were a part of the party, as well as famous members of her team, like Scooter Braun and Alfredo Flores. The photobooth pics from the night are the definition of adorable.
