Breaking NewsKelly Preston, Stacy Keibler, Lucy Liu and Renee Zellweger couldn't lock George Clooney down ... it reportedly took the power of a sexy law vixen to take him off the market for good.
Clooney and Amal Alamuddin dined at Nobu Thursday in Malibu and she was spotted wearing what LOOKED like an engagement ring. They dined with George's good friends Cindy Crawford and her husband Rande Gerber.
According to the NY Post, the two were trying to keep their recent engagement a secret.
