The former TOWIE star, 29, took to Twitter to respond to criticism she received after posting an April Fool's joke.
On Friday (1 April), Maria joined lots of other celebs when she shared a joke with her 463,000 Twitter fans.
Referring to previous rumours that she was expecting twins (because of the size of her bump), the former glamour model wrote: "Me and @KelvinBatey555 would like to announce that it's not actually twins and we are preparing for a gang of 3!! #triplets."

However, not everyone saw the funny side...
As messages of congratulations flooded in, others saw through it, with one tweeting: "This is obviously April fools, but would be kinda cool if it wasn't lol."
But some seemed appalled, with one Twitter user blasting: "Wow what an awful April fool, all those that can't even conceive one child."
Another wrote: "As happy as I am for you, please think of those unable to conceive or lost during pregnancies."
Many jumped to defend Maria, including one who responded: "It's not sick at all, she's not said it to offend anyone and you're moaning at her. Some people can't take a joke."
Maria later confessed it was indeed an April Fool's joke, but not before posting a message to her fans about the backlash.
I think if people get offended about pregnancy tweets because they can't conceive. Maybe just unfollow me, I can't help your situation...— Maria Fowler (@MariaFowler) April 1, 2016
... I wish I could. We thought we wouldn't be able to and it's a horrible feeling. But please stop blaming me. I don't mean to offend you.— Maria Fowler (@MariaFowler) April 1, 2016

"... I wish I could. We thought we wouldn't be able to and it's a horrible feeling. But please stop blaming me. I don't mean to offend you."
Even then, some of her fans took umbrage, as one wrote: "You should be happy but to say you thought it wouldn't happen when you wasn't together long isn't a struggle, years & years is."
To which Maria hit back: "You don't know what was going on with my body so shouldn't make judgements when I had tests about it."
Maria is expecting her first child with pro BMX racer Kelvin Batey.
They shared their happy news via a cute Twitter post in March, featuring a photo of them wearing identical shoes, alongside a mini baby pair of shoes. And, of course, Maria's beloved dog Dave!
The caption read: "As it's Mother's Day, @KelvinBatey555 and I are pleased to announce a new addition is on its way later this year."
Maria shot to fame on The Only Way Is Essex alongside Lauren Pope, starring on the reality show for three series from 2010 to 2011.
