Here is a look at other celebrities who have been involved in bizarre commercial deals:
Gareth Bale: The Tottenham forward, who Real Madrid are interested in signing, trademarked his goal celebration - a move that could see him make an extra £3 million a year. The Welsh international can now use his 'Eleven of Hearts' celebration on merchandise.
Jimmy White: The snooker star changed his name to James Brown for the 2005 Masters as part of a sponsorship deal. He also donned a brown tuxedo - instead of his usual black attire - as part of his deal with a sauce manufacturer.
Victoria Beckham: The former Spice Girl and Peterborough Football club battled over the nickname 'Posh' in 2002. The club made an application to use the name on merchandise but Victoria Beckham came in with a counter-claim.
Wimbledon officials insisted their courts had been prepared the same way as in previous years as the grass continued to claim victims.
Seven players had already withdrawn on day three of the tournament when Maria Sharapova slipped during her clash with Michelle Larcher De Brito and went on to lose.
The Russian fell in a similar area to where Caroline Wozniacki had earlier fallen foul, and as she underwent eight minutes of treatment, a spectator was heard to shout "Sort the court out".
That added to a growing train of thought that the grass of Wimbledon may be a factor in the unusual rush of injuries.
Tournament officials denied that, though, with an All England Club spokesman saying: "There has been no change to the way we prepare the courts."
Former British number one Tim Henman also defended the state of the surface, telling the BBC: "The courts are in the same shape they always have been. It's bizarre how all these injuries are happening this year.
"I'm as interested as everyone else as to why there have been so many injuries as the courts are in fantastic shape."
Victoria Azarenka, the women's second seed, pulled out this morning after hurting her knee in a first-day slip, while Jo-Wilfried Tsonga, the men's sixth seed, called time after three sets of his meeting with Ernests Gulbis because of knee problems.
Steve Darcis (shoulder) had earlier made himself unavailable, while Maran Cilic (knee), John Isner (knee), Radek Stepanek (thigh) and Yaroslava Shvedova (arm) also either quit matches or could not start.
World number one Maria Sharapova, who is famed for her grunting on court, takes on Sabine Lisicki at Wimbledon today - the tennis player who accused her own second round opponent, Bojana Jovanovski, of grunting so loudly it was "off-putting".
Lisicki, 22, from Germany, complained to umpire Mariana Alves about the noise during their match last week.
The Women's Tennis Association are currently reviewing plans to drive "excessive grunting" out of the game for future generations.
The pair will meet on Court One at 1pm this afternoon.
