Selena Gomez is eager to get back to work following her stint in rehab.

The 21-year-old former Disney star, who checked into a treatment facility in Arizona for two weeks last month, has been reading lots of scripts and attending casting calls in a bid to move forward.

A source told E! News that the brunette beauty is doing ''so well'' now and is concentrating on reading scripts so she can find another acting project.

The 'Come & Get It' hitmaker was spotted leaving an audition with a script and a big smile on her face in Studio City, California on Monday (03.02.14).

But the source said that Selena hasn't signed on to star in anything just yet.

She also hasn't decided whether she will reschedule the Australian leg of her 'Stars Dance' tour, which she cancelled in December to focus on herself.

The singer decided to seek treatment after her family expressed concern when they saw pictures of her with ex-boyfriend Justin Bieber on a Segway early last month.

The source said that the duo's on/off split was extremely tough on her emotionally but she is doing much better after taking time to clear her head.

The 'Spring Breakers' star previously admitted she was eager to focus on acting instead of music.

Asked whether she had plans to stop singing, she said: ''Yeah, probably for a while, I wanna get more into film. I'm open to trying new things.

''I just did an action movie and a dark comedy and then a drama so I've been able to do really fun projects that are different.''
