Mars shared the exciting news on his Instagram account on Tuesday alongside a hilarious video announcing the special guests.
"I was trying really hard to make a cool your poster once we got confirmation on who's joining us on the finale of the 24k Magic Tour," he wrote on Instagram.. "But in my excitement I forgot I suck at arts and crafts. Swipe left for the official announcement."
"As of today I've decided I won't be joining Bruno on tour this Fall. I thought that after giving birth to my daughter that 6 weeks would be enough time for me to recover mentally and physically. I also thought that I'd be able to bring her with me on tour, but I think I underestimated this whole mommy thing," Cardi wrote at the time. "Not only am I just not ready physically, I'm not ready to leave my baby behind since the doctors explained it's not healthy for her to be on the road."
Mars was very supportive of the new mom, sending her a personal message and saying, "Most important thing is you and your family's health. I know the fans will understand. You are absolutely doing the right thing I also know we'll share the stage when the time is right."
The duo has great chemistry on stage, performing their funky tune, "Finesse," at the 2018 GRAMMY Awards earlier this year. Take a look back at the stellar performance in the video below.
