Categorically shooting down a rumor started by the New York Post, NYPD commissioner Raymond Kelly on Sunday said Mary-Kate Olsen will not be subject to questioning about the mysterious death of her friend Heath Ledger. "There is absolutely no indication" that investigators need to grill Olsen, he said, given that those who actually stumbled upon Ledger's body - including housekeeper Teresa Solomon, masseuse Diane Lee Wolozin and the security team Olsen dispatched to the scene - have already been thoroughly Q&A'd. Kelly also confirmed it will be another week or so until Legder's toxicology report is back.

On Friday, Ledger's body was flown from New York to Los Angeles, where a Saturday-night memorial service was held at the Pierce Brothers Westwood Village Memorial Park. Michelle Williams (the actor's ex-fiancée and mother of his 2-year-old daughter Matilda) and Naomi Watts (with whom Ledger was previously involved) were among those in attendance.

At Sunday night's SAG Awards, There Will Be Blood's Daniel Day-Lewis dedicated his best-actor win to Ledger, touting the Aussie as a "unique, perfect" peer. ( See related news story.) Similarly, Cate Blanchett made a nod to Ledger while accepting the Modern Master Award at the Santa Barbara International Film Festival, hailing him as "an extraordinary actor [who] was well on his way to being a master himself."
