We've always loved Demi Lovato for keeping it real and giving zero f***ks about what anyone thinks.

So unsurprisingly, the star made no exception last Sunday night (February 28), when it came to partying at the Vanity Fair post-Oscar bash.

The star-studded annual magazine party was hosted this year by Graydon Carter, and took place as always in Los Angeles, California.

The 'Cool For The Summer' singer attended the event with her long-term boyfriend of over five years, Wilmer Valderrama.

She wore a sheer, floor-length black gown to party the night away with a host of other famous guests, including her bff Nick Jonas.

Lovato clearly had a lot of fun snapchatting throughout the entire evening, and fangirling with Brie Larson and Kerry Washington.

And later at the end of the night, she even ditched the heels and uploaded a photo onto Instagram of herself with her new friends Jessica Biel and Amy Adams all laughing and shoeless.

Lovato recently treated fans to another look at her upcoming new music video for her latest single 'Stone Cold'.

It is due to land on Tuesday (February 23), but the US star has now given fans a second preview.
