The 33-year-old singer - who married Brandon in October 2013 - recently admitted she isn't planning to have more than two children because she has struggled with being pregnant.

She said: "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."

Brandon also has two other children, Savannah and Seth, from a previous marriage.
