"Legally Blonde" leading lady Reese Witherspoon is now legally attached to produce and star in the romantic comedy "The Proposal," about wedding plans that go awry.

A writer has just been attached, and the project is underway for Revolution Studios, according to the Hollywood Reporter.

Witherspoon, 28, also is developing "Sports Widow," about a wife who sets out to surpass her mate in his knowledge of sports -- which sounds remarkably like the premise of the first "Legally Blonde."

Meanwhile, this fall, the star is due to be seen in the remake of the of the classic William Makepeace Thackeray novel "Vanity Fair" -- for which her tummy had to be concealed, because shooting took place last summer while she was pregnant. (Witherspoon and husband Ryan Phillippe welcomed their second child, a son named Deacon Phillippe, last October.)

"We've had a couple of scenes where my stomach was peeking out a bit, but we've found solutions," Witherspoon said last year.

She said she hid her stomach by wearing voluminous period dresses -- the story is set in the 1820s -- and standing behind strategically placed pieces of furniture.
