The former Pussycat Doll revealed the news of her second pregnancy on Instagram by posting a picture of her two-year- old daughter Willow holding onto her bump, alongside a balloon rabbit.
"There's a little bun-ny in the oven. Happy Easter," she captioned the picture.
Rogers also posted the photo on the photo-video sharing app and wrote, "My THREE girls... And a balloon bunny. Happy Easter everyone!"
Kimberly and Max tied the knot in February 2014 and welcomed daughter Willow in December the same year.
