Penelope Scotland Disick is already a fine diner!

Kourtney Kardashian and beau Scott Disick brought their newborn baby girl — along with her big brother, Mason, 2 — to Nobu in Malibu, Calif., to celebrate Kylie Jenner‘s 15th birthday on Friday night.

Holding her son’s hand, Kardashian showed off her post-baby body in a a polka-dot blue blouse and slimming black pants.

But baby Penelope was tucked out of sight.

Carried in a convertible car seat by Disick, Penelope was cozy under a baby blanket as the family of four made its way into the posh eatery.

Kardashian and Disick — who have been dating for six years — welcomed their second child on July 8, and have wasted no time showing off their beautiful daughter.

The proud parents have posed with Penelope on Us Weekly‘s cover; and they stepped out with the newborn earlier this week during a shopping spree in Los Angeles.

After feting with a Nobu feast, Jenner was seen leaving the restaurant with loads of birthday presents. Her older sister, Kendall, 16,  joined the celebration, bringing along some of the sisters’ mutual friends.

How do you think Kardashian looks post-pregnancy? Sound off in the comments.
