Selena Gomez wants it all or nothing at all. A source says that the "Love You Like a Love Song" singer is urging Justin Bieber to take anger management classes or they will not work out. After his egg-bombing prank got him into lots of trouble, his on-and-off girlfriend is fed up with his behavior.

New Year, new Justin? At least that's what Selena Gomez hopes as she is worried about her love's bad boy behavior. His recent egg stunt resulted in his home being raided, $20,000 worth of damage to his neighbor's home and the arrest of friend Lil Za for the possession of illegal substances. A source told Yahoo! Omg! that Selena is over it.

"Selena has told him 'no romance with new manner' and insisted that he should take a course in anger management. Selena is an old fashioned southern girl from Texas and believes in manners and good behavior," the source says. Event though the "Love Will Remember" star loves Justin (allegedly), "he has to mend his ways if they are to seeing each other regularly again," the source added.

No clue as to who this source is, but she seems to be very confident about what Selena said and what she wants. Gomez is mature beyond her years, so she only deserves a man who compliments her class and grace. "[Selena] is eager to make her reconciliation with Justin permanent, but only if he adjusts his attitude, she wants some pleases [and] thank yous, as well as some good behavior if things are to get serious again."

So if you were wondering what Selena's opinion about this whole huevo chaos, there it is, she is not laughing at this prank at all. JB, man, you have your lady back, let's take some action in keeping her around. Selena seems to be pretty adamant about anger management. Hope the "All That Matters" singer can turn his act around -- not only for her, but for the sake of his own reputation.
