Ring the Alarm! Medics Sent to Beyonce's Trailer

Just before midnight yesterday, paramedics were called to Beyonce's trailer on the New Jersey set of her new film "Cadillac Records" -- but it was her mom, Tina Knowles, who needed the medical attention.

TMZ spoke exclusively to Beyonce's father, Matthew Knowles, who said medics were called because Tina has the flu and began to experience shortness of breath. Paging Janet Jackson!

Matthew tells us Tina's blood pressure was a little high and she was checked out by medics -- but she was not transported.
