Pop star Selena Gomez, who has displayed her acting skills in the past, says acting is her "first love", but is not confident about it.

The 21-year-old is planning to put more effort into her film career, reports contactmusic.com.

"Initially I wanted to quit music, but that probably isn't ever going to happen. I think I need to do more acting. I'm not super-confident in it, but acting is my first love," Teen Vogue magazine quoted Gomez as saying.

"It's too easy for me to be in a teeny bopper movie. I like a challenge. 'Spring Breakers' is my proudest achievement, for sure, in acting. I'm so proud of my show ('Wizards of Waverley Place'), too, but the movie was absolutely liberating and it was awesome," she added.
