Gregory "Greg" Rusedski (born 6 September 1973, in Montreal, Quebec, Canada) is a British Canadian former tennis player who turned professional in 1991 and played until his retirement on 7 April 2007, at the age of 33. He is a former British No. 1 and ATP World No. 4.

Rusedski now provides commentary and analysis on the BBC's Wimbledon coverage.

Rusedski's first career singles tournament title was at the Hall of Fame Championship in Newport, Rhode Island in 1993.

Rusedski reached the singles final of the US Open in 1997, where he lost to Pat Rafter in four sets, (shortly thereafter reaching his career high rank of World No. 4). He also won the BBC Sports Personality of the Year Award.

In 1998, Tim Henman eclipsed Rusedski as Britain's number one tennis player. Rusedski, however, won the Grand Slam Cup in 1999.

Rusedski was defeated in the second round of Wimbledon in 2005 by Joachim Johansson of Sweden 7–6, 3–6, 6–4, 7–6. Following that disappointment, Rusedski had a successful July. He successfully defended his title at the Hall of Fame Championship, defeating Vince Spadea in the final. This was the first time he had successfully defended a title and the third time he had won the championship. He then reached the semifinals at both the RCA Championships in Indianapolis, losing to Taylor Dent, and the Canada Masters tournament in Montreal, losing to Andre Agassi.

Marcelo Andrés Ríos Mayorga (born December 26, 1975) is a former World No. 1 tennis player from Chile. Nicknamed El Chino ("Chinaman") and El zurdo de Vitacura ("Vitacura's Lefty"), he became the first Latin American player to reach the top position on the Association of Tennis Professionals (ATP) singles rankings in 1998. He held the World No. 1 ranking for six weeks. He has held the top ranking in both juniors and seniors. He was the first player to win the three clay-court Masters Series tournaments (Monte Carlo, Rome, and Hamburg) since the format began in 1990. He is the only male player in the open era to have been World No. 1 while never managing to win a Grand Slam singles tournament in his career. He did reach the 1998 Australian Open final, losing to Petr Korda.

He retired prematurely in 2004, after being overtaken by a back injury. He played his last ATP level tournament while only 27 years old at the 2003 French Open.

Ríos began playing tennis at the age of 11 at the Sport Francés golf club in Vitacura (Greater Santiago), adjacent to his house.

Peter "Pete" Sampras (/ˈsæmprəs/; born August 12, 1971) is a retired Greek–American tennis player and former world number 1. During his 15-year tour career, he won 14 Grand Slam singles titles and became recognized as one of the greatest tennis players of all time.

Sampras debuted on the professional tour in 1988 and played his last top-level tournament in 2002 when he won the US Open, defeating rival Andre Agassi in the final. He was the year-end world no. 1 for six consecutive years (1993–1998), a record for the open era. His seven Wimbledon singles championships are also an Open Era record. He spent 286 weeks at no. 1, the most of any male player. His five US Open singles titles is an Open Era record shared with former world no. 1 players Jimmy Connors and Roger Federer. Sampras is the last American male to win Wimbledon (2000) and the ATP World Tour Finals (1999).

Timothy Henry "Tim" Henman OBE (born 6 September 1974) is a retired English professional tennis player and former British Number One. Henman played a serve-and-volley style of tennis that suited the grass courts of Wimbledon. He was the first player from the United Kingdom since Roger Taylor in the 1970s to reach the semi-finals of the Wimbledon Men's Singles Championship. Henman never reached the finals of any Grand Slam but having reached six Grand Slam semi-finals, won 15 career ATP titles (11 in singles and 4 in doubles), and been ranked number 4 in the world, Henman was one of Britain's most successful open era male tennis players. He retired after helping Great Britain defeat Croatia in a Davis Cup match played in September 2007. Nicknamed "Tiger Tim", Henman is worth £17 million and remains a celebrity among the public.

Tim Henman comes from a talented sporting family: his father Tony, a solicitor, was accomplished at various sports, including tennis and squash. His mother Jane, a dress designer, played Junior Wimbledon and introduced Tim and his older brothers Michael and Richard to tennis as soon as they could walk on the family's grass tennis court. His great grandfather played at Wimbledon. His maternal grandfather, Henry Billington, played at Wimbledon between 1948 and 1951, plus representing Britain in the Davis Cup in 1948, 1950 and 1951. In 1901 his maternal great-grandmother, Ellen Stanwell-Brown (or Ellen Mary Stowell-Brown), was reputedly the first woman to serve overarm at Wimbledon. His maternal grandmother, Susan Billington, appeared regularly at Wimbledon in the 1950s, playing mixed doubles on Centre Court with her husband Henry, reaching the third round of the ladies' doubles in 1951, 1955 and 1956.

Kristina Lenko (born October 4, 1980), is a Canadian professional ice dancer. She competed internationally for Canada with Danny Moir before turning professional.

Lenko was born in Meadow Lake, Saskatchewan, on the family grain farm with her three sisters - her sister Joanna is also an ice dancer, and sisters Katherine and Sarah are also former skaters.

A student of the piano, Lenko received First Class Honours from the Royal Conservatory of Music in Toronto for Grade Nine Piano.

She was married to eight time British Champion skater Steven Cousins. They married on June 28, 2003 at their home in Barrie, Ontario, Canada. The couple separated in summer 2006 and later divorced^{[citation needed]}.

Before Dancing on Ice, Lenko's hair was below her waist. Needing something shorter, she went to her stylist in Toronto and told him "Do whatever you like." The result was an asymmetric Bob cut, which has been heavily copied, even by Victoria Beckham, as pointed out by Jayne Torvill on the Australian series of Dancing on Ice.
