Rihanna delivered an electrifying and hit-heavy half-time show at Sunday's Super Bowl, but social media went into meltdown when the singer revealed an unexpected special guest.

During an interview last week the “Diamond” singer was asked if she’s planning on collaborating with a special guest to which she answered, "I'm thinking about bringing someone," she replied. "I'm not sure, we'll see."

And while most fans speculated whom that special guest maybe, some considering JayZ, Drake and even Beyonce, the real guest turned out to be even more special.

Turns out it’s great news for the Fenty-Mayers family as the trio is getting ready to welcome the fourth addition to their family!

Adorned in an all red jumpsuit Rihanna kicked off the Half Time show with her show stopper “Better Have My Money” where she’s seen rubbing her baby bump as the camera pans away from her.

Congratulations to Rihanna & A$AP Rocky on their great news!
