Kylie Jenner has never been happier, 'overwhelmed with joy' with baby Stormi, source says (exclusive)

Kylie Jenner is loving being a mother.

The 20-year-old reality star welcomed her first child, daughter Stormi, in February, and a source tells ET that Jenner has never been happier.

"Kylie is overwhelmed with joy and love after welcoming Stormi into her life," the source says.

Jenner has been telling friends that she's "never been so happy," the source adds.

As for Jenner's relationship with rapper Travis Scott, our source says the two are also stronger than ever.

"Kylie and Travis are in a really good place," the source says. "Travis is very hands-on, and knows it's also important to treat Kylie special. Whenever the two get free time, they make it a priority to have date night. The Kardashian-Jenner clan loves watching Stormi whenever they get the chance."

Having a baby also apparently hasn't kept the makeup mogul from slowing down when it comes to her work.

"While Kylie was pregnant and after giving birth she has never stopped working," the source says. "Kylie has an incredible sense of work ethic and a knack for business."

Last week, Kylie shared adorable new photos of herself cuddling with Stormi.

ET recently spoke with Jenner's BFF, Jordyn Woods, who shared why she's so supportive of Jenner as a mom.
