SANTA CLARA (CBS SF) -- Levi's Stadium is still under construction, but it's already hit a milestone with its first marriage proposal.
Scott Onick was touring the new stadium with his girlfriend Sarah Cookson when he proposed to her with a message on the jumbo screen.
Sarah was completely surprised by the proposal.
"Oh my god, that's the most beautiful thing I've ever seen in my life. I've been freaking out. You were acting so strange," she said.
Both are loyal 49ers fans.
