“I guess because I’m a bigger gal …

I always got asked, ‘Is that a baby bump?’

And I’m like, ‘No, that’s just me.'”

She also shared viaInstagram, “You all know how long I’ve wanted this!!!!

@darylsabara and I are so beyond happy and excited to meet this little cutie early next year!

WE’RE PREGNANTTTTT!!”

“I just watch what I eat now.

I write everything now.

I check my blood.

And we’re good now.

I’ve been crushing it.

It’s like a game for me and I’m winning.

It’s nice to know we’re both healthy” she explained.
