Jesse James Better Hide...

According to the New York Daily News, Betty White is LIVID at Jesse James for cheating on Sandra Bullock.

White and Bullock co-starred in last summers "The Proposal", and they became friends. So when Betty heard the news about Jesse's affairs, she became irate.

"Betty wants to kick Jesse James' a--," a source close to White explains. "Betty is furious and just cannot understand why he would be so stupid. 

"He had everything. A beautiful, talented wife who adored him, an amazing daughter that Sandra treats as her own, and he has thrown it all away for some floozy."

The story goes on to say that White, 88, cannot utter Jesse's name without cursing.  And you just KNOW Betty White can curse with the best of them.  I bet she knows words that even sailors and mafia guys have never heard.

Remember ... there are some universal rules out there: You don't tug on Superman's cape.  You don't spit into the wind.  And you DON'T upset Betty White...
