The Pretty Little Liars star and wife Kim have welcomed their second daughter, the actor announced via Twitter on Friday.

“It’s a girl!!! And she’s as beautiful as her mommy and [3½-year-old] big sister Mabel,” Lowe, 44, writes. “We are blessed!”

The couple, who married in August 2010, announced the pregnancy in June.

“I’m trying to bank some sleeping hours, which is a little tough,” Lowe joked to PEOPLE last Saturday, sharing that his wife was due to deliver this week.
