Kate Middleton may have just indirectly confirmed that she’s not pregnant with baby number four. The Duchess of Cambridge stepped out in public on Wednesday to visit the National History Museum.

For the outing, Prince William’s wife wore a pair of Jigsaw khaki culottes and a long-sleeved aubergine Warehouse top. Middleton accentuated her look with her Chanel bag and maroon heels.

The mom of three let her hair loose during the outing. She also tucked her curls neatly while talking to the museum staff. Photos of Middleton from her recent engagement confirms that she’s not expecting another child with Prince William.

Not only did Prince George’s mom’s waist look very small during her outing, but her stomach was also very flat. Throughout the past couple of months, rumors have been swirling that Middleton is expecting her fourth child.

If the rumors are correct, Middleton would already be past her first trimester. But based on how flat her stomach is, it is impossible for her to be this far along or to even be pregnant altogether.

Months ago, a photo of Middleton seeming sporting a growing baby bump made headlines. At that time, the Duchess of Cambridge was hanging out with her three children at Prince William’s charity polo match.

In one of her photos from the outing, Middleton is carrying Prince Louis in her arms. And eagle-eyed royal fans noticed that Middleton’s abdominal area is enlarged. But over time, it has been proven that photo was just a bad angle for Prince William’s wife.

If Middleton was confirmed to be pregnant at that time, she would already be four to five months pregnant by now. After all, Prince William and Prince Harry’s charity polo match took place in July.

And during one of her previous engagements, Middleton was asked if she and her husband are planning on having another baby. She said that having a fourth child soon would make her husband worry.
