Congratulations to Christina Milian who welcomed her first child, a baby boy, with her boyfriend, Matt Pakora

"And so we begin," she shared on Instagram, alongside a photo of her beautiful little bundle of joy. "Isaiah 1/20/20 Simply perfect. The world is yours Son. Love, Mom & Dad."

Christina is also mother to her daughter Violet Madison, 9, whom she shares with her ex, The-Dream. Christina and Matt have been dating since 2017, and Isaiah will be Matt's first-ever child.

Christina announced she was pregnant back in July by sharing a photo with Matt holding up a sonogram. "New release 2020! What a blessing!" the former Disney star captioned the picture, before adding, "Let's do this babe!"

The singer/actress had her baby shower earlier this month in Westwood Village, California, and her celeb friends showed up to support her. Attendees included Khadijah Haqq McCray and Malika Haqq, Nicole Williams, and Olivia Pierson. Congrats!
