Kris Jenner has been trolled after she broke down in tears after her daughter Kylie revealed she was pregnant.

The Kylie Cosmetics CEO, 24, announced she and boyfriend Travis Scott, 30, are expecting in an Instagram video on Tuesday. During the clip, Kylie revealed the moment her three-year-old daughter Stormi presented Kris, 65, with a white envelope containing ultrasound pictures.

As Stormi handover the envelope, Kris, who was clad in a bright fruit pyjama co-ord, said: "Oh, what is this?" before pulling out the scan pictures.

Filing through them, a shocked Kris asked Kylie: "Are you pregnant?!" before becoming overwhelmed with emotion.

Through tears she said to her granddaughter: "Stormi, we're going to have a baby!" before adding: "This is one of the happiest of my life."

Kylie's second child will be Kris' 11th grandchild.

Mother-of-six Kris' eldest grandchild is daughter Kourtney's son Mason, 11. Kourtney, 42, also has Penelope, nine, and Reign, six.

Kim, 40, has four children; North, eight, Saint, five, Chicago, three, and son Psalm, two, while Khloe, 37, is proud mum to True, three.

Kris' only son Rob, 34, has a daughter Dream, 4.

The momager's emotional reaction prompted some shady social media commenters to suggest she was more happy she has another child to "market."
