Rihanna Baby: Chris Brown Congratulates Singer After Giving Birth

Chris Brown also hopped in to congratulate his ex after she gave birth to her baby boy.

"Congratulations," Brown said in his Instagram story on Thursday, according to a Page Six report.

The singer also included three emojis in the post, including a pregnant woman and praying hands.

Brown and Rihanna dated in 2007, but they broke up after two years when the "Don't Wake Me Up" singer physically assaulted the Fenty CEO.

The two reconciled in 2012, but Rihanna called that choice a "mistake" in a 2013 interview.

 In Brown's 2017 documentary entitled "Welcome to My Life," the singer noted that Rihanna did not trust him following the assault he committed.

Rihanna Pregnancy

Rihanna's pregnancy was first announced at the end of January this year when the "Rube Boy" singer was photographed with her boyfriend walking around in New York City.

During that time, Rihanna was wearing an archival Chanel jacket that was most unbuttoned, revealing her baby bump.

Rihanna then sported several glamorous pregnancy outfits.

In March, the singer opened up about how she embraced the physical changes that occurred to her as she underwent her pregnancy journey.

The singer noted that her face got a little round and chubby, and her nose started to spread.

She then claimed that being a mother is challenging.

The Barbadian singer noted that getting dressed while pregnant and doing her makeup is a challenge after getting pregnant, but she enjoys it.

"But I like challenges. I like things that force me to be creative and create in new ways. And with beauty, there's so much that you can do," Rihanna underscored.
