Former Amagansett resident Chris Martin and his band Coldplay performed a “secret” concert Sunday at that Hamptons town’s Stephen Talkhouse, in a SiriusXM-sponsored show to benefit the Wounded Warriors Project.

Entertainment Weekly said Monday that stars attending the 75-minute concert included supermodels Karlie Kloss and Christie Brinkley, with her daughter Sailor Lee Brinkley-Cook; rapper and music mogul Jay-Z, his pop star wife Beyoncé and their 4-year-old, Blue Ivy; and “Real Housewives of New York” stars Kelly Bensimon and Bethenny Frankel.

The concert, which featured such Coldplay catalog songs as “Yellow,” “The Scientist,” “Clocks,” “Fix You” and “A Sky Full of Stars,” was broadcast live on the satellite radio network’s channel The Spectrum.

The East Hampton Star added that the show, which SiriusXM contest-winners also attended, will be rebroadcast several times this week.

Coldplay used Jack’s Stir Brew coffee bar across the street as its VIP lounge, the paper said.
