Selena Gomez has pulled out of an event to promote her new movie Monte Carlo as she undergoes "routine tests" in hospital.
The pretty star, who is dating Justin Bieber, was taken to a Los Angeles medical centre on Thursday (09Jun11) after experiencing headaches and nausea following an appearance on The Tonight Show with Jay Leno.
Doctors kept her in overnight and were still conducting tests on Friday morning (10Jun11), prompting the Disney star to scrap a TV performance with her band The Scene in Santa Monica, California.
Gomez had been billed to take part in a Monte Carlo Experience event at the Santa Monica Place Center Plaza. The promotional bash will now go one without her.
