What better to celebrate a new job than dinner with a pal over chips and salsa and margaritas!

Selena Gomez channeled her Mexican heritage over dinner at Ernie's Mexican restaurant in North Hollywood Friday night. The singer-actress signed on for a new film, The Voyage of Doctor Dolittle, it was announced earlier in the day. She's been busy as of late -- besides her recent two-week stint in rehab for anxiety and depression, she has a Woody Allen (is he still working???) film coming out later this year and the third installment of Hotel Transylvania coming up. All that, and juggling an on-again-off-again romance with Justin Bieber!

Selena and a pal hit up the low-key NoHo eatery for some girl time last night and Selena was looking absolutely lovely. Her dress was casual but romantic and graceful and she paired it with her trusty block-heel mule sandals. What we noticed is the leather pouch necklace around her neck. Wonder what's inside!!!
