Ready for No. 3! Bristol Palin shows off her baby bump

In the photo's caption, Palin wrote, "3 weeks left," referring to her May due date.

It's the third child for the "Dancing With the Stars" alum, who married Meyer last June after a bumpy engagement.

The couple welcomed 1-year-old daughter Sailor Grace in December 2015. Palin also has a 7-year-old son, Tripp, with her ex, Levi Johnson.

Last month, Palin, 26 — the daughter of former Republican vice presidential candidate Sarah Palin — let fans know the family's newest addition will be another little girl.
