Real-life members of the high-society Guinness family led the stars attending the premiere of new Netflix series, House Of Guinness, held at London's Picturehouse Central on Tuesday night. Lady Mary Charteris, Daphne Guinness, Lord Ned Iveagh, Ivana Lowell, Jasmine Guinness and Celeste Guinness put on an eccentric group display as they posed on the appropriately dark-brown carpet. The socialite, 38, is the youngest child of James Charteris and his first wife Catherine, who is the daughter of Guinness heir Jonathan Guinness, 3rd Baron Moyne. According to Netflix, the series 'explores an epic story inspired by one of Europe's most famous and enduring dynasties - the Guinness Family.' Jack - who plays Byron Hughes - kept things classic and smart in a dark blue suit completed with collared shirt and a matching navy tie.
