Cardi B and husband Offset are a happy couple as they welcome their second baby. The rappers shared the news on Instagram on Monday, along with photos of the newborn.

First, the 28-year-old rapper shared a photo featuring Offset and the baby.

The mother of two covered the newborn baby in a blue cloth and wrote, "9/4/21" in the caption, along with a dinosaur, blue heart and teddy bear emojis.

Many celebrities took to the comments section to welcome the newborn and share their wishes.

While actor Justin Theroux liked the post, Kris Jenner simply wrote, "Congratulations!!!!!" with eye-heart popping emojis. Musical artist Billionaire B commented, "Congrats we love you sis."

Jamaican musician Shaggy also congratulated the couple. Actress Taraji P. Henson noted that the newborn baby is a Virgo, "A VIRGO YAAAAASSSSS CONGRATS!"

He shares Kalea with rapper Shya L'Amour, Kody with his ex-girlfriend Oriel Jamie and Jordan with Justine Watson, who sued the rapper for child support in 2017.
