Kim Kardashian has hit back at suggestions she doesn't spend enough time with her daughter.

The reality TV star -- who is currently accompanying her fiance Kanye West around the U.S. on his Yeezus tour -- lashed out at one critic on Twitter and insisted their five-month-old daughter, North, is with her 24/7.

The brunette beauty was furious after one of her 18.8 million followers apparently questioned her bond with North in response to a tweet she posted on Saturday.

It had read: "We took our baby girl swimming today for the 1st time, she loved it so much! #BestDayEver."

Then, in response to one of her fans, she ranted: "u sound so ignorant. Bc I don't tweet or instagram my every move w my daughter means I am not with her 24/7? We share what we want. Or is it bc I go support my fiance at every show & I post pix? When the baby goes down 4 bed or a nap, parents are allowed 2 work & support each other, maybe even have fun too."

Kardashian, 33, has attracted criticism of late for attending Kanye's concerts every night.

The couple also enjoyed a lavish shopping spree at The Webster boutique in Miami on Saturday morning.

An onlooker said: "People on the street were going crazy to get a glimpse of them. They were lined up around the block."
