LOS ANGELES: Hollywood star Alec Baldwin and his wife Hilaria have welcomed their fifth child together.

Hilaria shared the news in a post on Instagram on Wednesday.

"We had a baby last night. He is perfect and we couldn't be happier. Stay tuned for a name," she said alongside a photo of parents and the newborn.

Alec, 62, later shared the same photo, adding the Spanish caption, "Numero Cinco esta aqui. (Para mi, nu´mero seis)," which translates to "Number five is here. (for me, number six)."

Alec and Hilaria, 36, who tied the knot in 2012, are already parents to seven-year-old Carmen Gabriela, five-year-old Rafael Thomas, four-year-old Leonardo Angel Charles, and two-year-old Romeo Alejandro David.

Alec also shares 24-year-old daughter Ireland with actor Kim Basinger.

The two were married for nine years from 1993 to 2002.
