After the birth of their baby son, Kourtney Kardashian and Travis Barker are overwhelmed.

According to People, the Kardashians star is “over the moon” over the arrival of her son. She had her first child with drummer hubby this week.

The insider went on to claim that even though her pregnancy “took a stressful turn,” the founder of Lemme “feels so blessed” to have another joyful child.

“She is happy to just be able to snuggle her baby boy now,” the insider stated.

A lot of media outlets confirmed Kardashian’s fourth child’s birth on Saturday.

She has three children with her ex-husband, Scott Disick: Penelope, 11, Mason, 13, and Reign, 8.

Meanwhile, the drummer and his ex-wife Shanna Moakler have three children: Landon, 20, Alabama, 17, and Atiana, 24.

Kardashian and Barker have yet to comment on the arrival of their baby, who is expected to be named Rocky.

The 44-year-old reality star announced her pregnancy to the crowd during a Blink-182 concert in June by holding up a cardboard sign that read, “TRAVIS I’M PREGNANT.”

The couple later revealed the gender of their child at a rock ‘n’ roll themed celebration.

Barker abruptly departed Blink-182’s European tour in September to be with his wife during “urgent fetal surgery.”
