The 'Breakaway' hitmaker insists she has no plans to have another child after she has given birth to her second one because her body is "not made to be pregnant".

When asked if she wanted to add to her brood after this one, she told Australia's KIIS FM: "Oh, no, we are done. Oh good Lord, yes, I can't be pregnant again. This will be our number four total, so we're good ... Honestly, the first one was really rough, and I was like, 'Oh, it can't happen again,' and no it happened, like, way worse this time.

"I just get hospitalised, and I have to get fluids. It's just, like, my body was not made to be pregnant. I wish I was like the girl that ... it's beautiful, but it's not."

Meanwhile, the 33-year-old singer - who has 20-month-old daughter River Rose with husband Brandon Blackstock and is also stepmother to his two children - previously revealed she suffers from hyperemesis gravidarum, which causes pregnant women to suffer serious nausea and vomiting.

She explained previously: "I'm familiar with all-day sickness. I have to get IVs and fluids because I get so dehydrated. It's really bad."
