New York, New York - Rapper Cardi B had a big weekend and she used her performance alongside SZA as a chance to take baby Wave out with her for a concert adventure!

Cardi B made a special appearance at SZA's Madison Square Garden concert on Saturday. The two performed I Do from Cardi B's 2018 debut album, Invasion of Privacy, to the delight of the rowdy crowd.

But the Grammy-winning rapper and proud mother of two didn't show up to the concert on her own – she had her adorable one-year-old son, Wave, with her!

The WAP rapper shared snaps and clips from her Saturday night to Instagram on Sunday, with the caption: "Lit nights wit sza and Wavey."
