"I'm really disappointed. In fact I'm going back to the States to get them re-done."
Explaining why she isn't impressed, Katie continued: "They look fine in bra but they hang too low when I'm standing up and it's really bad when I'm lying down. There's about a four inch gap.
"I've had three boob jobs done before and I've seen enough other ones to know what they should look like and they're not right.
"I've also got indents so you can see where the implant is sitting and there's excess skin so the doctor either hasn't filled the skin up enough or he hasn't removed enough skin."
But the surgery, which has been booked for six months time, means she will have to delay plans for another baby.
Katie added: "This is the other annoying thing – he said he will re-do it in six months and then there's the recovery time after that and it means I won't be able to have another baby for 18-months, so it's set that back as well."
