Angela Simmons is officially a new mother.

The "Growing Up Hip Hop" star announced on Instagram that she has given birth to a baby boy.

In a photo of her holding her son, she wrote, "The best part of life has just begun Motherhood #ImSoInLove." She also included emojis of a heart, baby and engagement ring emoji.

The model and fashion designer hasn't exactly identified the father of her child, but most believe it to be Atlanta businessman Sutton Tennyson, whom she is engaged to.

In May, Angela announced she was pregnant on Instagram, showing a photo of her baby bump while hiking.

"We are overjoyed and super excited to receive a blessing this big!," she wrote. "Starting a family was something that I could have only dreamed of. ❀️"

In June, she revealed she was having a boy.

Angela often documented the pregnancy via social media. In early September she shared images from a sweet baby shower at the Sugar Factory in New York.

"Today was filled so much love ... Friends and family!!!," she ssaid. "Wow thank you everyone who came today:) thank you @sugarfactory for hosting us β€οΈπŸ’•β€οΈ."

At the shower, guests dined on finger foods and a slew of cupcakes, candy and other desserts. They also took photos in a photo booth.

Last April, Angela announced she was officially off the market, while showing off her giant diamond sparkler.

"YES!! I couldn't be more excited, she captioned the video in which her new bauble is the star of the clip. "This is only something I could of only dreamed of. I'm over the moon and feeling so blessed to be able to share my life with the one I truly love. Everything happened in the most perfect way."

She also used several emojis to indicate how happy she was.

Her father, Rev Run of Run DMC, seemed thrilled, too.

"Congrats Angela!!! Daddy loves you!!! I'm so happy for you!!," he tweeted after she posted her video.
