Kevin Federline is a Cry Baby!

Kevin Federline learns the hard way that nothing good can come out of reading your own reviews:

Kevin Federline has publicly put on a brave face despite his poorly reviewed debut rap performance at the August 20th Teen Choice awards, but insiders tell Us Weekly he’s devastated. “He was actually crying,” says a source. The next day, at home in Malibu, California, wife Britney Spears, 24, “also cried for him…She didn’t leave him alone all day,” says the source. (Their rep had no comment.)

It sucks when you discover that you aren't as good as your wife's ex. Maybe Karma wouldn't bite you in the ass for having such a big mouth either. Remember saying: "I'm going to be the next Justin Timberlake, only better". and ... "I'm gonna 'pulverise' Justin on the charts."

tsk tsk!
