Cardi B won't hit the road after all.

On Thursday night, the Invasion of Privacy rapper announced she has decided to forgo the 24K Magic Tour with Bruno Mars. Cardi, who just gave birth to her first child several weeks ago, said she was not physically nor mentally ready for the trek, which is set to kick off this fall.

"I also thought that I'd be able to bring [Kulture] with me on tour, but I think I underestimated this whole mommy thing," she wrote on Instagram. "[...] I'm not ready to leave my baby behind since the doctors explained its not healthy for her to be on the road."

Shortly after Cardi shared the news with fans, Mars posted a message of his own. Unsurprisingly, the "Finesse" singer expressed his support for the new mother, stating she was "absolutely doing the right thing."
