Kourtney Kardashian is rumored to be pregnant with child number three.

Spotted leaving Barney’s of New York in Beverly Hills on Thursday, which carries high-end nursery accessories as well as top fashion brands, Kourtney Kardashian, 34, carried a huge shopping bag.

Pushing her one-year-old daughter Penelope in a black and white pram, Kourtney Kardashian looked sleek in a navy blue shirt and wide-legged jeans.

Although she was seen on Wednesday looking particularly tired, Kourtney Kardashian showed no signs of fatigue on her shopping trip.

With her hair slicked back into a modern, feminine take on the pompadour hairstyle, her skin glowed with the tan she picked up on a family holiday to Mexico earlier in July.

Flat black pumps proved a sensible shoe choice for a shopping trip, and she continued to keep things simple by wearing minimal jewellery.

Three-year-old son Mason and long term boyfriend Scott Disick chose not to accompany the girls on their day out, although the family of four are often seen together.

However, they may soon be a party of five if the rumors of a third pregnancy prove true.

According to OK! magazine, Kourtney Kardashian and Scott Disick has already shared their joyful news with friends.

“Kourtney has confessed she’s expecting,” a source told OK.

“She’s very excited and only telling a select few right now – but she just couldn’t keep it quiet any longer.”

The source says that Scott Disick and Kourtney Kardashian had always planned to have another baby right after Penelope arrived.

“Kourtney has that kind of glow she had with Mason and Penelope… they wanted to have one right after Penelope,” the insider added.

During their recently vacation to Mexico, it was noticed that Kourtney Kardashian routinely avoided drinking alcohol and eating raw fish – two tell-tale signs of pregnancy.

Scott Disick and Kourtney Kardashian were reportedly inspired to add to their family after Kim Kardashian, 32, gave birth to daughter North West in June.

“When Kourtney first held Nori, a huge look passed between her and Kim, who turned to Scott and joked: <<Uh-oh>>

“Scott knew exactly what she was <<thinking>> They would be next!”

“Nori was the tiniest baby either of them had ever seen,” added the source.

 “Automatically their parental protection thing totally kicked in. They can’t wait to have another little one!”

Meanwhile, potential father-to-be Scott Disick grabbed lunch in Beverly Hills, attracting attention in his bright yellow Rolls Royce.

The enormous convertible is said to cost around $500,000 and is hardly the most family-friendly vehicle, although that shouldn’t prove a problem for Scott Disick, who owns a fleet of cars and may well be glad of the excuse to buy yet another one.

Later Scott Disick joined Kourtney Kardashian and his young daughter to continue their shopping trip.

The couple stopped off at LA favourite Freg Segal and Kourtney Kardashian picked up a pink smoothie drink to keep her energy up.

The couple took turns to tote baby Penelope, who was dressed for the hot weather in patterned grey leggings and a loose-fitting white top.

Experts in keeping the romance alive, Kourtney Kardashian and Scott Disick made sure to fit a little kissing time into their busy day.
