Carrie Underwood & Michael B. Jordan Help Open Atlantic City's New Hard Rock Hotel!

Carrie Underwood performs on stage during a concert at the Hard Rock Arena on Friday (June 29) in Atlantic City, N.J.

The 35-year-old singer held her first big comeback show that night following her injury last year.

“Had soooo much fun tonight playing the @hardrockhcac !!! Atlantic City, you were so good to us!! ❤️🔥❤️,” Carrie wrote on Instagram after the show.

Carrie‘s son Isaiah was at the show and it was his first time watching his mom perform a full show!

The new Hard Rock Hotel & Casino just opened up in Atlantic City and a big weekend bash was held to celebrate the launch. Michael B. Jordan was at the hotel’s Daer Nightclub on Thursday night for a celebration and Pitbull headlined the arena on Saturday night.
