With the words “20 weeks” scrawled in the sand, that pro surfer, 27, struck a pregnant pose with her 2-year-old son Tobias.
“20 weeks along and feeling excited everyday!” she wrote. “For those who don’t know 20 weeks is about halfway along in pregnancy.”
Earlier this month, Hamilton announced her second pregnancy with husband Adam Dirks.
The pair – who were wed in Aug. 2013 – welcomed their first child on June 1, 2015.
Bethany Hamilton lost her arm in a 2003 shark attack. Hamilton wrote about her experience in the 2004 autobiography Soul Surfer: A True Story of Faith, Family, and Fighting to Get Back on the Board. Then in April 2011, the feature film Soul Surfer was released.
