Sheryl Crow was upbeat and friendly as she signed autographs outside a Hollywood hotspot Wednesday night, just one week after undergoing breast cancer surgery.


The beloved star was out and about, leaving what inside sources tell us was a party in her honor. Famous friends gathered together to support the singer's battle, including Courteney Cox Arquette and Laura Dern.


Sheryl Crow was also the talk of the red carpet Wednesday night in Beverly Hills at the Power Benefit sponsored by Saks Fifth Avenue.


A bevy of A-listers such as Lisa Kudrow, Diane Lane, Lisa Rinna, The Black Eyed Peas, Steven Spielberg, Natalie Cole, Ellen DeGeneres, Rita Wilson and Tom Hanks all sent their well wishes to Sherly Crow.

"There's millions of survivors out there; make it one million and one,"

Hanks said.


Inside the event, "Extra" caught up with breast cancer survivor Melissa Etheridge, who was toasted by Hanks.

"She moved us with her courage to rock the house,"

Hanks said.


Melissa was then presented with the EIF Women's Cancer Research Fund Courage Award, for which she graciously said,

"I wish you love, I wish you peace and light. Thank you all very much."

Ellen DeGeneres, whose mother is a breast cancer survivor, later took the stage, where she congratulated Etheridge for her honorary award.

Today, "Extra" has learned that Sheryl may seek treatment near Nashville, where her family lives. We've also learned that Sheryl's ex, Lance Armstrong, has been in touch by phone and e-mail.

"He's extremely concerned,"

revealed Peter Castro, People's executive editor.

"And she's extremely grateful for that concern."

Lance Armstrong, a famous cancer survivor, is playing a hands-on role in Sheryl's recovery. "He's been talking to people in his organization to get Sheryl the very best care," Castro said.


While Sheryl had to postpone her concert tour, fans can look forward to a brand-new acoustic performance: her new hit, "Always on your side."



Less than two weeks before Valentine's Day, rocker SHERYL CROW and super cycler LANCE ARMSTRONG called it quits. The seven-time Tour de France bicycling champion and the Grammy® winning musician were set to get married this year, and Crow had even posed in Allure magazine in a VERA WANG wedding dress talking up the nuptials. Cheryl Crow and Armstrong officially became an item back in early 2004 and got engaged in September 2005, when Lance Armstrong proposed to Cheryl Crow in Sun Valley, ID, not long after he retired from the pro circuit in July. But rumors that there was trouble in paradise began surfacing around the holidays, and on February 3 the couple released a statement to the press confirming the split.
