Rihanna's boyfriend A$AP Rocky is just as much of a fan as the rest of us!

During her Super Bowl halftime performance on Sunday, the "Lift Me Up" singer, 34, showed off her growing baby bump in a surprise pregnancy reveal.

Rihanna could also be seen caressing her stomach during the performance. The singer’s representative confirmed the pregnancy shortly after she ended her 13-minute set.

A$AP Rocky — whom she already shares a 9-month-old son with — proudly cheered from the sidelines in a video shared by the NFL on Twitter. 

In the clip, he put on his flashlight during her performance of "Diamonds" before bopping back in forth as he listened to Rihanna's music. The "Praise the Lord" rapper, 34, threw his hands in the air and clapped towards the end of the video.
