Tulsa's Mix 96.5 says,

CALABASAS, Calif. — Actor Jason Momoa was involved in a head-on collision with a motorcyclist in Calabasas on Sunday morning, California Highway Patrol confirmed.

According to officers, the “Aquaman” star was not injured, but the motorcyclist was knocked off his bike and sustained minor injuries, KABC-TV reported.

Authorities confirmed that Momoa, who was driving a 1970 Oldsmobile, stayed at the scene to help the injured motorcyclist and flagged down a passing driver to call 911, the TV station reported.

The motorcyclist has been identified as 21-year-old Vitaliy Avagimyan, who was traveling westbound on Old Topanga Canyon Road when he crossed the double yellow lines into the road’s eastbound lanes and directly into the path of Momoa’s oncoming Oldsmobile, KTTV reported.

TMZ has video of the aftermath.

He's ok. Hope the motocyclist will be fine. I don't know much about cars but uh though a 1980s Oldsmobile isn't some 1950s American car where you just rinse of the bumper and keep moving, it's no light weight.

Yeah, it's a 1970, though. I believe my parents had the same car (they had a 1970 or 71 Cutlass Supreme, gold with white interior), or one pretty close to it. They were beasts! I had a 1969 Delta 88 in my 20s, and my high school had a brand new 1985 Custlass the year I took driver's ed. OMG I loved driver's ed so much that year. haha My mom later had a 1973 or 74 Cutlass, white with black interior, and that black is NOT a good idea in Oklahoma heat! Vicious!

Seems like everyone is going to be alright.
