The 25-year-old sports star, who survived a horrific shark attack in 2003 which resulted in losing her arm, revealed the exciting news via her Instagram page to her some one million followers.
Alongside a beautiful snap with her husband Adam Dirks and newborn bub the Hawaiian-born beauty wrote: “Blessed to welcome our son, Tobias, into the world. Born June 1st, 7.9 lbs. and 21″ Long.”
“He is named after his great grandpa Tobias meaning ‘The goodness of God.’ Adam and I so in love with our lil guy and are stoked to share life with him! #stokedmomma Photo:@TimmyHamilton.”
In the touching image the proud new parents cradle little Tobais who is swaddled in a white blanket. The new family of three are surrounded by lush greenery, mountains and water – presumably in their native Hawaii.
The happy couple, who tied the knot in August 2013, announced they were expecting a bub in February.
“I’ve been surfing throughout my whole pregnancy. I plan to surf as long as I can,” Bethany said at the time.
“Once the belly’s pretty big maybe [I’ll] just like mellow it out and spend more time swimming and just enjoying the ocean and doing other activities,” she mused.
Congratulations to Bethany and Adam on your beautiful son.
