Annabeth Gish

Brotherhood star Annabeth Gish has formed a brotherhood of her own following the birth of her second son over the weekend.

Enzo Edward Allen arrived Saturday, Oct. 25, in Rhode Island (where Gish shoots the Showtime drama), People reports. The newborn, who weighed 7 pounds, joins big brother Cash, 21 months.

Dad is Gish's husband Wade Allen.

And talk about perfect timing - the third season of Brotherhood premieres Sunday at 8 pm/ET.
