"Best. Thing. Ever," Schulman wrote alongside a picture of himself cradling the newborn. "Cleo James arrived at 6:01 a.m. weighing 6 lbs. 10 oz. Shout out to my baby mama @el_peego for delivering this bundle of joy."

Perlongo also posted a picture, featuring the whole family in a hospital bed.

"I don't remember this photo being taken or anything about the last 24 hours, but bb girl has finally arrived," Perlongo wrote. "She's everything."

Just one week ago, Perlongo was flaunting her baby bump, decorating it as an island with a pair of palm trees, a sandcastle and a tiny pair of flip flops while reclining in a bathtub.

"Baby's due any day now!" Schulman wrote in the caption for the pic. "Totally obsessed with this woman but definitely going to miss this adorable baby bump. @el_peego #wcw"

Perlongo also bared her bump as she walked the red carpet at August's MTV Video Music Awards, wearing an open gray jacket and silver body chain.
