Blonde bombshell Mollie King has hit back at the trolls who have been criticising bandmate Frankie Sandford's pregnancy weight gain.

Sandford, who announced that she is expecting a baby back in May, has come under fire over the past few weeks for putting on the pounds and even admitted to struggling with the rude comments, but King has now slammed those respsonsible for the cruel jibes and told Yahoo! OMG:

"When you're pregnant obviously you're going to be larger than you were before because you've got a little baby in there! She's really positive about it and she's doing really well. I think she's about five months, she's doing really well. She's really glowing and very happy. I just want to meet that little one now."

"I get really impatient, I'm like, 'Oh my God nine months is ages!' so I just want her to push it out so I can meet the little one."

Sandford recently confessed: "I'm having to get used to my body changing. If I wasn't on stage and being photographed all the time, I think I'd be more relaxed. There are a lot of things to get used to. You can look good from one angle and not another. I think black is definitely the way forward with my pregnancy."
