has been spreading the news about giving birth – by text messaging her friends.
"I got a text from her the other night. 7 lbs, 7 oz., and everyone is healthy and happy," Josh Lucas told PEOPLE at Tropfest@Tribeca.
Hayek gave birth
to her daughter Valentina Paloma Pinault Sept. 21.
"For someone you care about and love as much as I love her, I was just so happy for her," Lucas, who dated Hayek
for about nine months, said.
This is the first child for Hayek, who is engaged to the baby's father, François Henri Pinault. If the Ugly Betty
star's love for her dogs is any indication, Lucas knows Hayek will be an excellent parent.
"She will be a doting and loving mother. The way she is with her dogs, I can't even imagine what she'll be like with her kid," Lucas said before the festival Sunday night.
Lucas plans to visit the first-time mother and baby in a week and a half, he told PEOPLE.
Lucas was a guest judge at the free public event that featured sixteen short films. The original Tropfest – and world's largest short film festival – takes place in Sydney.
