Rihanna performed at the Super Bowl Halftime Show on Sunday, February 12.

She made a huge reveal during her performance, and her ex Chris Brown reacted.

Brown wrote "Go Girl" in a vague post after his ex's performance.

He did not tag Rihanna or mention her name on the update.

The 34-year-old songstress revealed her second pregnancy while performing at the Super Bowl.

She opened with "B**ch Better Have My Money" and performed other hit songs.

Rihanna wore a red ensemble and diamond earrings with her hair styled into a ponytail.

Brown congratulated her after her son's birth in May 2022.
