Some context: Yao Ming (Chinese: Yao Ming ; born September 12, 1980) is a Chinese former professional basketball player who played for the Shanghai Sharks of the Chinese Basketball Association (CBA) and the Houston Rockets of the National Basketball Association (NBA). He was selected to start for the Western Conference in the NBA All-Star Game eight times, and was named to the All-NBA Team five times. At the time of his final season, he was the tallest active player in the NBA, at 2.29 m (7 ft 6 in). He is the only player outside of the United States to lead the NBA in All-Star voting.
Yao met Chinese female basketball player Ye Li when he was 17 years old. Ye was not fond of Yao at first, but finally accepted him after he gave her the team pins he had collected during the 2000 Summer Olympics. She is the only woman he has ever dated. Their relationship became public when they appeared together during the 2004 Olympics closing ceremony. On August 6, 2007, Yao and Ye married in a ceremony attended by close friends and family and closed to the media. On May 21, 2010, the couple's daughter Yao Qinlei (whose English name is Amy) was born in Houston, Texas. In 2004, Yao co-wrote an autobiography with ESPN sportswriter Ric Bucher, entitled Yao: A Life in Two Worlds. In the same year, he was also the subject of a documentary film, The Year of the Yao, which focuses on his NBA rookie year. The film is narrated by his friend and former interpreter, Colin Pine, who stayed with Yao during Yao's rookie year, and interpreted for him for three years. In 2005, former Newsweek writer Brook Larmer published a book entitled Operation Yao Ming, in which he said that Yao's parents were convinced to marry each other so that they would produce a dominant athlete, and that during Yao's childhood, he was given special treatment to help him become a great basketball player. In a 2015 post on the website Reddit.com, Ming stated that this was not true and that he started playing basketball for fun at age 9. In 2009, Yao provided the voice for a character of a Chinese animated film The Magic Aster, released on June 19. Yao enrolled at the Antai College of Economics & Management of Shanghai Jiao Tong University in 2011. He is taking a tailored degree program with mostly one-on-one lectures to avoid being a distraction on campus.
did they divorce?
A:

IN: Gifford was born in Santa Monica, California, the son of Lola Mae (nee Hawkins) and Weldon Gifford, an oil driller. He graduated from Bakersfield High School. Following Gifford's death in 2015, his wife Kathie Lee Gifford said that her late husband grew up in a poverty-stricken home and that he and his family sometimes ate dog food. She said they lived in 29 places even before Gifford attended high school because his father could not find work during the Depression.

Gifford married his college sweetheart, USC's homecoming queen Maxine Avis Ewart, on January 13, 1952, after she became pregnant while they were students at USC. They had three children, Jeff (b. 1952), Kyle and Victoria, and five grandchildren. Victoria married Michael LeMoyne Kennedy, son of Robert F. Kennedy. Gifford was then married to fitness trainer Astrid Lindley from 1978 to 1986. The first two marriages ended in divorce. Gifford married television presenter and singer Kathie Lee Johnson, who was 23 years his junior, on October 18, 1986. The couple settled in Greenwich, Connecticut, with their son, Cody Newton Gifford, and daughter, Cassidy Erin Gifford. Gifford and his third wife Kathie Lee both shared the same birthday, which was August 16. The couple co-hosted ABC's coverage of the 1988 Winter Olympics in Calgary. Gifford had an older sister and younger brother, Winona and Waine. In 1997, the tabloid magazine Globe arranged to have Gifford secretly videotaped being seduced by former flight attendant Suzen Johnson in a New York City hotel room. They published photos and stories. ESPN reported that the tabloid paid Johnson $75,000 to lure Gifford to the room, while The Atlantic said it was $125,000. National Enquirer Editor Steve Coz observed, "There's a difference between reporting the news and creating the news ... [w]ithout The Globe, there would be no story here. I'm in the tabloid industry, and this is way over the top. It's downright cruel." According to the former lawyer of Johnny Carson, Henry Bushkin, Gifford had an affair with Carson's second wife Joanne in 1970.
