Simmons was already five months pregnant when she announced the baby news in September. She told US that her family was excited and anxious to meet the little girl but telling her father wasn't easy for her.
"I was so nervous telling my dad at first being that I'm not married YET but he was very excited and is supportive 100 percent," she said at the time. "His concern is just that I'm happy."
"We are both very excited about the birth of our first child," she added. "We totally were expecting it to be [a] boy all along but got very surprised when we found it was indeed a girl. I immediately went out and brought a cute [little] outfit for her right after the appointment."
Simmons announced she was expecting a daughter on Instagram when she shared a picture of her sonogram. She has been dating Mike Wayans, the son of actor Damon Wayans, for eight years. The next step for the couple is marriage, she told Essence magazine in October.
"Of course we talk about that and it's looking good," she said. "But I don't want to be a pregnant bride. I wanna have a beautiful wedding, hopefully a destination wedding where I can show off my figure in a beautiful long flowing dress."
Simmons appeared on the MTV show "Run's House" from 2005 to 2009 with her family and a spinoff show with her sister Angela Simmons called "Daddy's Little Girls."
Simmons and Wayans have not released baby photos of Ava Marie yet.
