Gomez vows never to change for a guy

Selena Gomez would never change for a guy again - after she 'lost herself' in one relationship.

The 19-year-old singer-and-actress– who is dating teenage singing sensation Justin Bieber – admits she once let a boyfriend's likes and dislikes influence the way she behaved, and after witnessing how happy her loved ones were when the romance ended, she insists she will always be herself from now on.
