Cardi B has announced she will no longer be accompanying Bruno Mars on his 24K Magic World Tour.

The rapper, who gave birth to her first child earlier this month, said she "underestimated the whole mommy thing" and needs time to mentally and physically recover from labour.

She also explained that attending the tour would mean leaving her newborn daughter behind - something she is not prepared to do.

She said that while it was a difficult decision, she ultimately had to prioritise her own wellness and that of her baby.

Sorry guys ,Thank you @BrunoMars for being so supportive and understanding .Your the best ❤️❤️❤️ pic.twitter.com/ds9HE61i9j

Cardi has built up a reputation of being a workaholic, having filmed several music videos, promoting her album and performing at Coachella all throughout pregnancy.

She received praise from fans for putting baby Kulture's needs first.

The star was also supposed to headline Longitude this year but had to pull out as it was too close to her due date.

Bruno Mars enlisted Cardi for his world tour following the success of the pair's collaboration, 'Finesse (Remix)'.
