Selena Gomez was rushed to hospital Thursday night. The singer-and-actress - who has been dating Justin Bieber since the beginning of this year - reportedly felt ill while taping an interview with chat show host Jay Leno and was taken to a Los Angeles hospital immediately afterwards.

Sources told gossip website TMZ, Selena, 18 was complaining of nausea and a severe headache and is currently undergoing tests. The exact cause of her illness is not yet known.

Meanwhile, Selena revealed during her chart with Jay on The Tonight Show that her parents, Mandy and Rocardo - who divorced when she was five - are huge fans of her boyfriend: "He passed the test."

Justin's family also approve of Selena after he took her on a recent trip to his hometown of Stratford, Ontario in Canada to meet his family. "Justin and Selena had lunch with Justin's cousins and his aunt and uncle. They were really sweet and make an adorable couple. They looked happy and in love. They acted just like everyday people, very down-to-earth. Justin is part of the community, he's one of us and is as friendly as can be," said a source.
