Kourtney Kardashian puts pregnancy talk to rest in high shorts and a tight waistbelt as she tags Mason and Penelope along for a birthday party

She's been fielding speculation that she could be adding another youngster to her brood.
But Kourtney Kardashian looked happy to be putting any and all baby chatter to rest as she stepped out in a well-fitted ensemble on the streets of the east Hollywood neighbourhood of Los Feliz, California on Sunday.

The mother-of-two made sure to dispell any new pregnancy rumours by capping it all off with a tight leather belt wrapped tightly around her ribcage.
Kourtney twinned her outfit with a simple necklace and a few Cartier love bracelets.

The eldest Kardashian sister easily shielded her figure once she stepped out of the car, carrying baby Penelope at the hip and dangling a large birthday box beside her.

With her hair slicked back into a modern, frizzed pony tail, her skin glowed with the tan she picked up on a family holiday to Mexico earlier in July.

The reality star grabbed her three-year-old son Mason with her other hand, the youngster cutting a fashionable figure in a white vest top and orange cut off shorts and a pair of blue and purple Air Jordan trainers.

'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 and Kourtney 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.
