The Duchess of Cambridge, Kate Middleton, is once again rumored to be pregnant with baby No. 2. According to the most recent print report from The Globe, Middleton, 32, is expecting another baby with Prince William, 31. While the royal couple just welcomed their first child, Prince George, in July, the tabloid is now claiming that the duchess will instead welcome a baby girl and future princess this time around.

"Kate has already told William, 'I'm having a girl!'" a source revealed to the gossip magazine. According to the report, the exact gender of the rumored future royal has yet to be determined via an ultrasound, but the duchess is convinced Prince George will soon have a sister. "She's only 14 weeks along," said the insider, adding, "[But] she told William she feels so much different than her first pregnancy, when she had to be hospitalized with severe morning sickness that plagued her for weeks."

So what would the future princess' name be? According to the rumors, the royal couple has already decided on the baby girl's moniker. "William has always said that if he ever had a daughter, he'd like to name her after his late mother, Princess Diana," said the source, adding that Queen of England, William's grandmother, agrees with the name choice. "Queen Elizabeth has given her blessing," said the insider, later adding, "As her Majesty faces her final days, battling heart woes and other health problems, she knows how much it would mean to William to honor his mom."

Middleton was last rumored to be expecting in January, when Star magazine reported that she was two months along with her second baby. "The royal family is overjoyed with the stunning turn of events," read the print report, adding claims that the duchess had her heart set on having a female heir. "Kate and William will, of course, be happy with a healthy baby of either sex, but Kate is really hoping for a girl this time," revealed a "royal insider," adding, "She feels a little sister for George would be perfect."
