Only ET was with Olivia Newton-John as the singer/actress and newlywed was honored at Project Angel Food's 15th Annual Angel Awards over the weekend in Hollywood. The award was bestowed for her commitment to breast cancer awareness.

Olivia opens up about her commitment to fighting cancer and reveals her desire to reach out to fellow breast-cancer survivor Christina Applegate. She also tells ET her new marriage is "wonderful."

The 'Grease' star was presented with the Marianne Williamson Founder's Award for her efforts in educating women on the importance of early detection of breast cancer and in making life easier for those fighting the disease.

In October, Olivia will release her new CD, Olivia Newton-John & Friends: A Celebration in Song, with proceeds from the album sales benefiting her Cancer Centre Appeal.
