The L.A.-based Chainsmokers finally returned for a homecoming show on Thursday night (June 14), their first since 2016, a lifetime ago for the award-winning, globe-trotting A-listers.

Jake Miller (left, the rising singer-model who's not afraid to post selfies while chowing down at In-N-Out) and dance star Jordyn Jones (4.5 million Instagram followers) were amongs those seeing the new stage show. The Chainsmokers have outgrown the DJ decks. Part of the expansion is drummer Matt McGuire (right), who has ascended to equal billing on stage like a third member of the duo.

Meanwhile in New York, other musical heavyweights gathered at the Songwriters Hall of Fame Induction Ceremony. Steven Tyler and Usher (both are reality TV singing contest alums) got close, as The Weeknd presented an award to Sir Lucian Grainge.

In D.C., Wolf Blitzer joined members of Playboy's first family (Current CCO Cooper Hefner and former CEO Christie Hefner) for the Hugh Hefner Foundation's 2018 First Amendment Awards.  The honorees included Simon Tam, the leader of the Asian-American rock band The Slants, who fought and won a seven year court battle against the U.S. government to trademark his band's name. The government had refused to register the mark because of the name's disparaging use as a slur.   

The new Rosé Day LA event in Malibu proved to be a popular excuse to sip pink wine in fancy clothes.

The opening of the new Domino Park in Brooklyn  brought out a wide swath of notables from former New York governor Elliot Spitzer (left) and actor Josh Lucas...

And "This American Life" host Ira Glass (with Anna Carson Blair). It's on the Williamsburg waterfront in the footprint of a former Domino sugar factory. Although privately owned by developer Two Trees, the new park is open to the public and not just those who live in the surrounding towers. The Party Report's Brooklyn surrogates report that cooped-up condo dwelling locals have been antsy for the new park for months.

Brooklyn cool: Volleyball, bocce, and food from an affiliate of Shake Shack are part of the six acres across from Manhattan.
