"You never know who you're going to meet at dinner parties!! Great night! So much fun, thank you Cade!" Spears captioned the photo.
The image features the pop stars smiling as they lean in close together for the photo. Spears also shared a photo of her meal during the gathering.
Spears was presumably referring to her friend and publicist Cade Hudson in the caption, Billboard noted.
