The Duke and Duchess of Cambridge together with Prince Harry joined forces on Saturday, July 5, as they gave a royal send off at the start line for the iconic Tour de France. While giving this year's competitors a royal send off, Kate Middleton's fluffy face and alleged baby bump is becoming visible as she steps out at the Harewood House to formally begin the competition following its ceremonial start in Leeds city centre.

Prince William and Kate Middleton headed the ribbon cutting as they sent all the racers off as this year marks the 101st Tour de France. For the 2014 race, all riders will pass through the United Kingdom, Spain, and Belgium, and then will have its finish line in Paris, France.

While everyone is busy wishing all the cyclists a safe and exciting race, others can't help but notice Kate's puffy face. "Kate Middleton's face appeared much more puffy than it usually does, and the photos of Kate at the starting line have once again sparked rumors that the Royal couple is expecting another baby," Celebdirty Laundry reports.

Kate's sister Pippa Middleton reportedly hinted that the royal couple is expecting their second child during her recent appearance at the Matt Lauer show. She is allegedly telling a few people behind the set of the show that Kate is on its early stages of pregnancy and Prince George will be getting a new sibling, according to the gossip Web site.

While the world is busy speculating about her second pregnancy, the Duchess together with the Duke watched the stellar five-set Wimbledon men's final between seven-time Wimbledon champion Roger Federer and world number one Novak Djokovic. After almost four hours of intense match, Djokovic end up victorious in the fourth set.

The royal couple took a moment to greet the tennis champ after his victory at the 2014 Wimbledon Lawn Tennis Championships on Sunday, July 6, at the All England Lawn Tennis & Croquet Club in London. "It was amazing. Incredible tennis. Well done," William told Novak as he congratulates the new Wimbledon champion.

"Many congratulations. That was fantastic tennis. It was such a finish," Kate added. And when Djokovic asked her how her tennis skills, the humble brunette replied, "I'm slightly out of practice at the moment since having George."
