Jenny Craig spokeswoman Valerie Bertinelli has been in the news a lot lately, announcing her 40-pound weight loss and high-fiving talk show hosts about her new lease on life. Bertinelli's ex-husband, Eddie Van Halen, is making news too. His story is not as bright and cheery as hers.

The band Van Halen has reportedly postponed four concerts while guitarist Eddie Van Halen undergoes medical treatment.

"The Van Halen concerts in Dallas, Cincinnati, Raleigh, and Baltimore have been postponed," reads a new message on the band's Web site. "According to Eddie Van Halen's physician, he is undergoing a battery of comprehensive medical tests to determine a defined diagnosis and recommended medical procedures."

In 2002, Eddie Van Halen announced he was cancer-free after a two-year battle with tongue cancer.
