The “Melissa & Joey” star, 36, and her husband Mark Wilkerson welcomed a baby boy named Tucker on Tuesday evening.
Baby Tucker weighed in at eight pounds, five ounces.
Melissa and Mark issued a statement about their happy news, saying, “Mom and Dad are elated and can’t wait to introduce him to his brothers.”
Hart and Wilkerson are already parents to two other boys – Mason, six, and Braydon, four.
Melissa Joan Hart has not yet decided on a middle name for Tucker yet, but they previously admitted they wanted to wait to see their baby before deciding on a name.
Melissa previously said, “We have a few favorite [names] – we keep tossing them around. I’m just to figure it out on the day. I don’t like to name them before because I’m like, “What if I change my mind?’”
Melissa announced her pregnancy back in April but she and her musician husband decided to wait to find out the sex of the babyt.
Hart previously stated, “We don’t want to know. We found out both other times, but this one we want [it to be] a surprise.”
