The video kicks off by explaining that the entire thing was shot over the course of a house/pool party that Lovato threw.

About halfway through, Hilton shows up in the DJ booth, and the party clearly kicks into high gear.

Hilton isn't the only celebrity to make an appearance in the video, however.

If you look closely, you'll also see singer/actor Jamie Foxx and Grammy-nominated rapper Wiz Khalifa.

Lovato recently shared a surprising picture on social media when she posted a photo of her with her ex, Wilmer Valderrama.

Even though they split one year ago, they are still good friends and they're not hiding it.

The two began dating back in 2010, but ended their relationship in June of last year. Afterward, Lovato was romantically linked to Luke Rockhold, a UFC fighter, before settling into a relationship with mixed martial arts fighter Guilherme 'Bomba' Vasconcelos.

Lovato and Bomba supposedly had a good relationship, with Lovato once said in an interview, "I'm just having fun; you know? And my life is in a really good place right now. He makes me laugh." But, the two split up recently.

While it seemed like Lovato and Valderrama were just casually enjoying each others' company, there's likely another reason they were spending time together.

The two actually have an animated film coming out soon that they perform in together. It's titled Charming, and it's described as follows:

"The film explores the untold stories of Snow White, Cinderella, and Sleeping Beauty who discover that they are all engaged to the same Prince Charming. After a fairy spills a large amount of charm dust on Charming, Prince Charming, led by the heroine Lenore, a woman who is incapable of love, must go on an epic journey to find his true, true love."
