Maria Shriver isn't the only member of the Kennedy clan who has given her stamp of approval to her son Patrick Schwarzenegger's new girlfriend.
Miley Cyrus and Schwarzenegger, 21, continued their week of partying in Miami, where they're attending Art Basel, with a wild night on Friday that included reconnecting with the singer's make-out partner from the previous evening, Paris Hilton, and dancing with Schwarzenegger's uncle, Anthony Shriver.
The escapades began with the new couple heading to The Shore Club for the Bootsy Bellows pop-up and Jesse Jo Stark performance before moving on to the private estate of JR & Loren Ridinger for the Art of Fusion event with artist Mr. Brainwash (a Cyrus pal).
While at the bash sponsored by Haute Living, Hublot and Dom Perignon, the lovebirds danced and drank with pals as well as actress Eva Longoria. Maria Shriver's brother, Anthony, 49, founder of the nonprofit Best Buddies, was also at the event and "was chatting and hanging out with the couple quite a bit," according to an eyewitness.
At one point Schwarzenegger's uncle even "picked Miley up and swung her around the dance floor," the eyewitness tells PEOPLE. (Cyrus's outfit for the night: a bodysuit emblazoned with a marijuana-leaf design and matching earrings, and at some point she ditched her jean shorts.)
Arnold Schwarzenegger's eldest son was spotted downing shots with the "Wrecking Ball" singer, and the pair asked a fellow partygoer to take snapshots of them on their phone.
The next stop was LIV nightclub in the Fontainebleau, where Cyrus, 22, and her actor-model beau caught up with the singer's new BFF Hilton and they partied with DJ David Guetta. At 5 a.m. the "We Can't Stop" singer and Schwarzenegger moved on to 24-hour nightclub E11EVEN – for the third night in a row.
