Glamour magazine awarded Němcová a "Survivor Award" in 2005 for the way she picked up her life following her tsunami ordeal; her comeback being complete with her appearance in the 2006 Sports Illustrated swimsuit issue. She also appeared in the 2007 British FHM calendar as Miss May. She is now the host of TLC's A Model Life. She wrote Love Always, Petra published December 2005, which tells of her early life under Communist rule in Czechoslovakia, her entrance into the field of fashion and modeling, and her breakthrough into Sports Illustrated, which was her springboard to becoming a supermodel. She also tells of her life with Simon Atlee and how they fell in love and became engaged to marry. Nemcova has also moved on romantically, briefly dating British singer James Blunt in 2006. On 7 July 2007 she was a presenter at the American leg of Live Earth and appeared in the music video 'Misfit' by American indie group Elefant. She is currently working with HP computers to produce a multi-million dollar TV and web campaign.
In July 2007, Němcová became a vegan after learning about the planet's rapidly depleting fish stocks. The Czech Republic-born model gave up meat and dairy in February of that year.
Also in July 2007, Němcová partnered with New York City power broker Ron Schnackenberg to form a luxury boutique real estate firm Aglow Properties, which specializes in representing high net-worth/high profile clients in a very discreet manor. Aglow Properties has been linked with several high priced New York City apartment transactions. On 12 November 2007 Nemcova visited Haiti alongside Haitian-born musician Wyclef Jean as part of a charity-sponsored event. The inauguration of a computer lab and an eatery in the slums of Port-au-Prince were funded and sponsored by Jean's Yéle Haïti foundation and Nemcova's Happy Hearts Fund. Němcová is signed to Chic Management in Sydney, Australia. Recently she traveled in Mykonos island to attend a party in honor of De Grisogono jewels and she also did a fashion shooting for the Greek edition of Hello! magazine. Nemcova is also signed to Next Models Management.
During the Indian Ocean earthquake of 26 December 2004, Němcová was at the Khao Lak resort in Thailand with her main photographer and fiancé, Simon Atlee when the tsunami struck where they were staying. Initially, Atlee was presumed missing, but his body was found and identified on 3 March 2005, on the shores of Sumatra (near the epicenter of the earthquake that caused the Tsunami). Atlee drowned, and Němcová suffered a broken pelvis and serious internal injuries, but she managed to hold onto the top of a palm tree, reportedly for eight hours, until she was rescued by Thai civilians and airlifted to an inland hospital nearby. Petra spent three weeks in a Thai hospital, and then flew home to the Czech Republic, where she spent an additional three weeks in the hospital. Atlee's body was not found until over two months after the tsunami. Němcová's first interview after her near-death experience was with Diane Sawyer on ABC's Primetime Live, on 9 March 2005. She has also spoken of her experiences on the Larry King Live program on CNN.
