We had no idea they were so close!

Kathy Hilton hosted her 59th birthday party at The Palms restaurant yesterday, and we caught a very dressed down Paris Jackson making her way into the bash. Vanna White was also in attendance, and to say it was an odd mix of people would be an understatement!

Speaking of Michael Jackson's daughter, rumor has it she's dating model Cara Delevingne. The two recently shared photos and videos from their cozy night in watching lesbian drama Carol in bed together, and all signs point to a new girl-on-girl romance. The pair were first linked over the holidays, and they've only gotten closer as time goes on.

"Cara is quite enamoured by the fact Paris is the daughter of one of her musical heroes. There’s a spark. She invited her as guest of honour to her Christmas Burberry X bash in London, before whisking her away to Venice then Prague the weekend after, where they celebrated Christmas early at the markets. They’re both really into their music and have been spending nights singing and jamming on the guitar," a source dished to The Sun.

Anyways, watch Princess P give a street singer a wad of $20s for singing her mom happy birthday in the below video! What a generous heiress, that Paris!
