Kate Middleton and Prince William have returned from their summer holidays in France along with their two children, Prince George and Princess Charlotte, a source told Hello! Magazine Tuesday. Over the last few months, Middleton has been surrounded with several rumors about her third pregnancy.

According to the report, the royals were away for just over a week and returned Tuesday as William is set to resume his shift duties at the East Anglian Air Ambulance charity, where he works as an air ambulance pilot.

Local media reports said that Middleton and William spent time with their friends while on their summer getaway. They also reportedly "spent a night" at the Hotel du Palais in Biarritz.

Last month, rumors surfaced that Middleton is pregnant with twin girls and is due this Christmas. However, the report by Life&Style magazine was debunked by Gossip Cop.

Meanwhile, several rumors have also made the rounds that Middleton will be taking over the royal duties from Queen Elizabeth II as the 90-year-old monarch is heading for a retirement, OK! Magazine reported. However, this report was also debunked by Gossip Cop.

Over the weekend, reports claimed that Middleton was flirting with British sailor Ben Ainslie in front of her husband the America’s Cup on July 24 in Portsmouth, England.
