Rita Ora and Chrissy Teigen Ate Doughnuts in the Park

By

Of all of the partygoers in New York and L.A. (and Las Vegas!) this week, Rita Ora and Chrissy Teigen appeared to have the most fun: On Tuesday, the documented cool girls trekked to Madison Square Garden, where they wore iridescent silver and fringe, and stuffed their faces with heart-shaped doughnuts, all in the name of DKNY’s latest fragrance.

They weren’t the only ones enjoying the final stretch of summer. In Bel Air, Liz Goldwyn, Rashida Jones, and Mandy Moore attended a New Balance–sponsored dance party, and, a few miles away, Leonardo DiCaprio (who, incidentally, was also wearing sneakers) demonstrated his commitment to marine life at Oceana’s annual SeaChange Summer Party. Meanwhile, Joe Jonas celebrated his 25th birthday with family in Las Vegas, and Kim Kardashian wore a jumpsuit to end all jumpsuits to a party honoring Donald Robertson in L.A. Back in New York, Maria Sharapova hosted a breast-cancer benefit with the CFDA and Porsche, while Kevin Durant showed up at Barneys to celebrate Russell Westbrook's limited-edition collection.
