Chad Michael Murray says his smooch with Lindsay Lohan in 2003's Freaky Friday was important not just for their characters, but for the actress herself — since it was her first-ever onscreen kiss. "I remember Lindsay and I were kids. I mean Lindsay was probably 16, I think. That was her first onscreen kiss," Murray, 43, tells PEOPLE. "That was a whole thing. That was super nerve-racking."
