The ex-Baywatch star and former Playboy Playmate had a "major fall" while searching for the Biblical boat in Turkey, with shocking pics revealing a bruised, blood face and puffy lips.
Donna was trekking on an "extremely dangerous part" of Mount Ararat (where the Book of Genesis indicates the Ark came to rest) in the Eastern European nation when she fell.
But according to TMZ, Donna isn't about to let a damaged visage come in the way of her search.
Sources told the entertainment website Donna is determined to finish the final two days of her risky trek before heading back to the States.
It's not the first time the former TV star has encountered trouble on her trip — Donna previously reported she was in "serious danger" from Kurdistani terrorist group the PKK.
The 44-year-old has a longstanding fascination with discovering Noah's Ark, telling AOL News last year that she's been "fascinated" by the boat "since I was 9 or 10".
She revealed she has been studying the whereabouts of the Ark for years and claims it lies broken in two or three pieces in an area close to where she has been trekking.
The former playmate has left her two children in the US while she "fulfils her dream" and reportedly plans to return to Turkey for another attempt at discovering the Ark next month.
