Prince William and Kate Middleton will be spending Halloween at the Law Tennis Association on Oct. 31.

The couple, who is both fans of tennis, will be watching various on-court sessions, including a wheelchair tennis demonstration. Middleton will also participate in the Tennis for Kids session, where she will help teach children between the ages of 5 and 8 how to play the sport, according to People.

Middleton will also have the chance to meet the top junior talents, as well as the members of various coaches, their trainers, nutritionists and physical therapists. The Duchess of Cambridge is not the only one from her family who is an avid fan of tennis. A few months ago, she revealed that her mom, Carole, has a crush on Roger Federer.

“Roger Federer is my mother’s heartthrob. I don’t think she will mind me saying that! I think he probably knows that too!” she told People.

Middleton also said that watching the Wimbledon has been a family tradition growing up. “It is such a quintessential part of English summer. I was really taken by Agassi and Sampras, Ivanisevic and Steffi Graf. That for me was my first memories,” she shared.

Meanwhile, Prince William and Middleton are not the only ones who will be spending their Halloween for a valuable cause. Prince Harry will also be traveling to Chicago to attend the Obama Foundation’s inaugural summit. Prince Harry will be reuniting with former President Barack Obama and his wife, Michelle Obama.

There are rumors suggesting that Prince Harry will be visiting his girlfriend, Meghan Markle, when he heads to the country. However, an insider claimed that Prince Harry will just go to Chicago for the inaugural summit and head back to his home thereafter.

Markle is currently in Toronto, filming for the upcoming eighth season of USA Network’s “Suits,” where she places the role of Rachel Zane. There are speculations that the actress will eventually give up her role to move to London and be with his boyfriend, according to E! News. However, Markle has not yet confirmed or denied these rumors.
