It's a boy for former "Saturday Night Live" star Rachel Dratch!

The comedian, 44, gave birth to her first son, Eli, at a Manhattan hospital Tuesday, a source confirms to UsMagazine.com.

"She's doing great and the baby's doing great," the source tells Us. "She's healthy and really happy!"

The actress debuted her growing baby bump in June as she posed on the red carpet with her then-pregnant pal Amy Poehler at the premiere of "The Kids Are All Right" in NY.

Dratch has not revealed the father's identity.
