This means war, indeed!
Before she set her sights on Ben Flajnik, current Bachelor bad girl Courtney Robertson dated more than one Hollywood hunk: former Desperate Housewives star Jesse Metcalfe, Adrian Grenier…and Reese Witherspoon's husband, Jim Toth!
Even Witherspoon, 36, didn't know about her man's long-ago dalliance with the catty reality star, 28 -- first learning the news Feb. 1 upon returning from a trip to Europe.
But it was no big whup to the Oscar winner. "It didn't faze Reese," a source tells the new Us Weekly of the star, who wed the CAA agent, 41, nearly a year ago.
"There's no way Jim was serious about Courtney," the source sniffs of the model. "How do you go from that chick to Reese?"
