Desiree Hartsock is going to be a mother of two.

The former "The Bachelorette" Season 9 star said in an Instagram post Wednesday that she is "beyond excited" to be having another baby with husband Chris Siegfried.

"The Bachelorette" alum is due in January 2019, and is uncertain if baby No. 2 will be her last.

"I think that's a bridge we have to cross after this one," she said. "We might be OK at two, but you need an army with more kids!"

Hartsock competed for Sean Lowe's affections on "The Bachelor" Season 17 before starring on "The Bachelorette."

Lowe ultimately picked Catherine Giudici, whom he married in January 2014.
