She's obviously a goddess.

"But why, Nanda, don't you enjoy leading the holy life? Why can't you keep up the holy life? Why, giving up the training, will you return to the common life?"
"Lord, as I was leaving home, a Sakyan girl — the envy of the countryside — glanced up at me, with her hair half-combed, and said, 'Hurry back, master.'
Recollecting that, I don't enjoy leading the holy life. I can't keep up the holy life. Giving up the training, I will return to the common life."
Then, taking Ven. Nanda by the arm — as a strong man might flex his extended arm or extend his flexed arm — the Blessed One disappeared from Jeta's Grove and reappeared among the devas of the heaven of the Thirty-three [Tāvatiṃsa]. Now on that occasion about 500 dove-footed nymphs had come to wait upon Sakka, the ruler of the devas.
The Blessed One said to Ven. Nanda, "Nanda, do you see these 500 dove-footed nymphs?"
"What do you think, Nanda? Which is lovelier, better looking, more charming: the Sakyan girl, the envy of the countryside, or these 500 dove-footed nymphs?"
"Lord, compared to these 500 dove-footed nymphs, the Sakyan girl, the envy of the countryside, is like a cauterized monkey with its ears & nose cut off. She doesn't count. She's not even a small fraction. There's no comparison. The 500 dove-footed nymphs are lovelier, better looking, more charming."
