Reese Witherspoon has agreed to star in the romantic comedy The Proposal.

According to Hollywood Reporter, she will also produce the film through her Type A Films for Revolution Studios.

The romantic comedy centres on a couple and their up-and-down journey as they plan their wedding.

It is based on a pitch by writer Nicole Eastman, who will begin writing immediately.

Revolution's Todd Garner will serve as executive producer and will oversee with Denise Decker.

"Reese and I have been looking to find something to work on together for a long time, and we are excited that we finally have that opportunity," Garner said.

He added: "This is a terrific project that fits perfectly into Reese's strengths."

Witherspoon most recently starred in Legally Blonde 2: Red, White & Blonde and next appears in Vanity Fair.
