Grammy- and Oscar-winning singer-songwriter Melissa Etheridge, a breast cancer survivor, has received a Hollywood Walk of Fame star.

Tuesday's ceremony in front of the Hard Rock Cafe Hollywood also marked the launch of Hard Rock's monthlong Pinktober campaign, a series of concerts and celebrity events held to raise money and breast cancer awareness.

The 50-year-old Etheridge is best known for the songs "Come to My Window" and "I'm the Only One." She received the 2,450th sidewalk star in Hollywood.

Etheridge, who was diagnosed with breast cancer in 2004, has been an artist ambassador for Pinktober for six years.
