"Happy two months my angel baby 👼🏽," Diamond wrote via Instagram on Monday, March 7.
In the sweet snapshot, the tot — who was born on January 7 — is wearing pink pants and a shirt that reads, "Dreaming." She also sported a pink headband and white cozy socks.
Of course, people couldn't help but gush over the newborn. One person wrote, "She is beautiful. God is so good. 🌈," while another added, "LOVELY IS SO BEAUTIFUL 😍 HAPPY 2 months precious love 💕."
A third person added, "Happy 2 Months Lovely 🥰🤎."
Five days prior, Diamond uploaded a photo with the child, writing, "I love u endlessly."
Diamond has been shy about posting her child on social media, but she has recently shared more photos, including one of Lovely on February 7.
"LOVE🤎you are my sun, my moon, and all of my stars. Happy one month my beautiful babygirl.. forever to go," she wrote.
"The princess is here! Lovely Symphani Brown," she wrote in January. "My sweet babygirl, it's been a whole day you've been in the world and have already shown me the true meaning of life. I promise to love and protect you always. Forever yours, mommy..."
Diamond revealed she was expanding her family in September 2021. "Just when you think you know love, something little comes along to remind you just how big it really is," she captioned a snapshot of her cradling her belly.
The "Forever" singer has yet to address the rumors that he is the father of Diamond's kid. Brown is also a father to daughter Royalty Brown, 7, and son Aeko Catori, 2.
Brown and Diamond were first linked when they were both spotted at a party in 2019. Afterward, Brown was caught flirting and "liking" Diamond's pictures, which didn't go over well with his second baby mama, Ammika Harris, who was pregnant with his second child.
As a result, Harris was apparently "pissed" that the musical artist was expecting a child with Diamond.
