Reese Witherspoon says "Legally Blonde 3" is officially a go.
The clip shows Witherspoon floating in a pool while wearing sunglasses and a pink bikini. Her look is similar to one Elle wears in the first "Legally Blonde" movie.
"It's true... #LegallyBlonde3," she captioned the post.
"Legally Blonde" opened in theaters 2001, and was followed by "Legally Blonde 2: Red, White & Blonde" in 2003.
"Legally Blonde" is based on the Amanda Brown novel of the same name.
Karen McCullah and Kirsten Smith, who adapted the book for the first movie, are said to be in final negotiations to write the new script.
