Melissa Joan Hart has a new man in her life: Her third son, Tucker!

The "Melissa & Joey" star -- already mom to Braydon, 4, and Mason, 6 1/2, with husband Mark Wilkerson -- welcomed the 8 lbs., 5 oz., baby boy Tuesday at 10 p.m., her rep tells Us Weekly. She tweeted about his arrival on Thursday, posting on Twitter, "Baby boy Tucker has finally arrived! We waited all year to meet this lil man&we could not be more excited & relieved that he is in our arms!"

Confirming her pregnancy in April, the ABC Family actress, 36, chose to keep her new arrival's gender a secret until giving birth -- and wasn't worried about being outnumbered at home if she had another boy.

"If I was to pinpoint one amazing moment in my life, it would be the moment when my boys met. Mason walked in, jumped on daddy's lap and looked at Brady in my arms on the hospital bed," Hart told Us in August as she neared the end of her pregnancy. "That was just a special moment, and I'm looking forward to that again."

Big brothers Braydon and Mason are just as excited as their mom to welcome little Tucker to the Wilkerson family fold. "I can't leave or go anywhere -- even to bed! -- without them kissing the baby goodnight or saying, 'Good morning, baby,' or reading books to the baby," '90s teen said Hart, herself the oldest of eight siblings.

Proud new parents Hart and Wilkerson tied the knot in Italy in July 2003.
