Ali Landry is a new mother of three! The 39-year-old TV personality welcomed a baby boy with husband Alejandro Monteverde on Thursday, July 11, a source confirms to Us Weekly.

The couple's bundle of joy weighed in around 8 pounds, and "mom and baby are doing great!" the source says.

Landry and her film director hubby, 35, married in April 2006. The spouses are already parents to daughter Estela, 6, and Marcelo, 21 months.

The former Miss USA tweeted a heads up to her Twitter followers on Thursday that she was in labor. "The time has come. Baby is on his way," she wrote with a smiley face. "On our way to the hospital." She later added, "Contractions are not too bad yet. I will try to do a live video later on [Hang With]. Follow me there to see how things are progressing."

Landry had already warned her fans that the baby would be arriving soon on July 1, sharing, "Just left the doctor. Countdown for baby has begun, 80% effaced, 2 centimeters dilated. Oh my goodness."

Throughout her pregnancy, Landry tweeted updates to her fans about how she was staying healthy. "Only a few weeks from delivering, and instead of giving up work out sessions decided to switch to water workouts," she wrote on June 12. "I am in love. Feels amaz!" 

In June, Landry told Us Weekly that likes to keep her family on a schedule. "I'm definitely a disciplinarian mom," she admitted. "I'm pretty strict and I don't let [the kids] sway me very much."
