Reese Witherspoon has sparked fresh marriage rumors after she was spotted wearing an engagement ring. The "Legally Blonde" actress - who has been dating Jake Gyllenhaal since 2007 - hastily removed the sparkler during a recent photo shoot when she realized people were staring at it.

A source at the Avon shoot, which was held at Los Angeles' Sony Studios, told America's Star magazine: "It was gorgeous, and everyone noticed it right away. But she took it off as soon as she saw people staring. Reese stuffed it in her bag and didn't put it on again the rest of the day."

Reese Witherspoon was "humiliated" by her divorce from Ryan Phillippe. The "Walk The Line" actress has admitted she reached the lowest point of her life when she split from the "Breach" actor in 2006 after seven years of marriage.

She said: "It was very humiliating and very isolating. But, by the way, if it's not painful, maybe it wasn't the decision to marry to begin with. Those are the appropriate emotions."
