Esther Daphna "Esti" Ginzburg-Keizman (Hebrew: אסתי גינזבורג; born 6 March 1990), is an Israeli fashion model. She has modeled in international campaigns for brands like Tommy Hilfiger, Burberry, FCUK, Pull and Bear, and Castro. She was also featured in the 2009, 2010, and 2011 Sports Illustrated Swimsuit Issue. According to Forbes Israel, she was among the top ten highest paid models in Israel, alongside top Israeli models such as Shlomit Malka, Gal Gadot, and Bar Refaeli.
Ginzburg was born and grew up in the Tzahala neighbourhood of Tel Aviv, Israel. Her father, Arik Ginzburg, is an architect, while her mother is a doctor, specializing in geriatrics. Her grandfather was an engineer involved in the original planning and construction of Tel Aviv. Ginzburg is Jewish. She attended the prestigious The Ironi Yud Alef High School in Northern Tel Aviv.
She began her compulsory military service in the Israel Defense Forces on 22 July 2009, and in early October of that year, while speaking in support of enlisting, caused headlines by criticizing fellow Israeli model Bar Refaeli for evading military service via a short-lived marriage to a family friend. On joining the army Ginzburg said: "Military service is part of the things I personally believe in." She subsequently studied international relations at the Hebrew University.
Ginzburg started modeling at the age of eight with a milk advertisement and at the age of 14 signed a contract with modeling agency Elite Models. In 2006, she signed a two-year deal with Israeli firm Fox, and was featured on the February/March 2007 cover of French Elle. She has also modeled in international campaigns for brands like Tommy Hilfiger, Burberry, FCUK, Pull and Bear, and Castro. She was also featured in the 2009, 2010, and 2011 Sports Illustrated Swimsuit Issue. Ginzburg made her acting debut in the 2010 Joel Schumacher film Twelve, which garnered negative reviews. In 2013, she appeared in the American comedy film, Movie 43, which was panned by critics and won the 2013 Razzie for Worst Picture. She was briefly a co-host on the Israeli reality singing competition show, HaKokhav HaBa, but was soon replaced by Rotem Sela.
Esti Ginzburg volunteers for the Hayim Association, which works to provide relief and support to children in Israel who are diagnosed with cancer.
On 8 June 2012, Ginzburg married Israeli real estate investor Adi Keizman. In February 2015, Ginzburg gave birth to their son, Refael Yehonatan.
On 18 December 2013, it was reported that Ginzburg's father was suing her for allegedly failing to pay him money owed for a house he sold her and her husband. She no longer has a relationship with her father after he sued her, and he has not met her son.
