Donning a dark ensemble – including sunglasses, a luxurious stole and a large peacoat – the 60-year-old model walked the couple’s dog for a walk near the apartment they shared in the city’s SoHo neighborhood.
Iman has quietly grieved the loss of her husband in recent weeks.
“She’s fine. We’re fine. We’re holding up,” Iman’s longtime friend Bethann Hardison told PEOPLE exclusively in January. “It comes in waves, you know. He’s a great loss – not just a loss as an artist, but as a human.”
His loved ones later chose to avoid a public memorial. “The family of David Bowie is currently making arrangements for a private ceremony celebrating the memory of their beloved husband, father and friend,” his family said in a statement last month.
The family also thanked fans, saying, “We are overwhelmed by and grateful for the love and support shown throughout the world.”
According to a statement released by CBS, “the tribute will be a multi-sensory testament to the superstar’s incredible artistry and a reflection of his limitless creativity.”
