Actors Meryl Streep, Cate Blanchett, Amy Adams, Julianne Moore and Joaquin Phoenix are among the mourners who gathered in New York on Friday (07Feb14) to attend the private funeral of tragic actor Philip Seymour Hoffman. Other celebrity friends and admirers, including Michelle Williams, Ethan Hawke, Ellen Burstyn, John Slattery, Mary Louise Parker, Jerry Stiller, Marisa Tomei and Spike Lee, were also spotted arriving at the Church of St. Ignatius Loyola in Manhattan's Upper East Side to pay their respects and say farewell to the Oscar winner, who died from a suspected heroin overdose on Sunday (02Feb14). An estimated 400 guests joined Hoffman's longtime girlfriend, Mimi O'Donnell, and their three young children for the service, which took place a day after friends, family and former co-stars remembered the 46 year old at a wake at the nearby Frank E. Campbell Funeral Home. The church where the funeral is currently taking place is the same venue where R&B star Aaliyah and former U.S. First Lady Jackie Kennedy Onassis' memorial services were held. The actor's family has asked for charity donations in lieu of flowers for The DreamYard Project and the Christopher & Dana Reeve Foundation - Hoffman's favourite causes. A larger, public memorial is expected to be held later this month (Feb14).
