x and y variables are from different data frame (ggplot2)

I'm learning ggplot2 so please excuse my novice understanding.

Is there a way to do a simple scatter plot when x and y are from two different data frames? For example:

p <- ggplot(data=df1, aes(x=x.in.df1))
p + geom_point(data=df2, aes(y=y.in.df2))

Since x.in.df1 does not exist in df2, when geom_point tries to look for x in df2, it fails.

EDIT: The reason why I hesitate to cbind is because I have many data frames with the same variables. For example, df2000 contains variables GDP, GDP growth for all countries in year 2000. df2001 is the same for year 2001.

Credit goes to @Roland; I'm just posting his comment as an answer here for future readers like myself who encounter the same/similar problems.

ggplot(data = data.frame(x = df1$x, y = df2$y), aes(x = x, y = y))

Thanks for the elegant solution @Roland.
