Eddie Van Halen is engaged to his girlfriend/publicist Janie Liszewski, PEOPLE has learned.


Van Halen, 53, proposed to Liszewski, 38, on Aug. 4 while they were vacationing in Hawaii. The rock guitarist dropped to one knee and popped the question in a private room at Tiffany's, a source close to the couple tells PEOPLE.

The couple plan to wed next June.

"They are happy, healthy, very much in love and looking forward to living life together forever," says the source. "They are devoted to each other and to experiencing life in a whole new, positive and passionate way."

It will be the second marriage for Van Halen. He was married to actress Valerie Bertinelli, with whom he has a 17-year-old son, Wolfgang. It will be the first marriage for Liszewski.

Van Halen returned to touring in April after missing a number of concert dates while undergoing tests for a mystery illness.

In 2002, Van Halen announced that he had recovered from tongue cancer.
