The girls both looked stunning at an Avon gala in New York last night

Courteney Cox and Reese Witherspoon both attended a benefit evening for the Avon foundation for women, and looked simply stunning.

Reese blew everyone away with her three-tone strapless number and strappy black stilettos.

We are always in awe that she manages to carry off that flawless with minimal effort look, with her chic and simple make-up and perfect blonde tresses.

Courteney also went for a strapless number, opting for a flowy below-the-knee layered dress.

She added sparkle to her outfit with her dainty necklace and glitzy bracelet, and we are seriously loving her black platform heels.

Whenever Bruce Springsteen does a concert, people beg him to play “Born in the USA.” For Billy Joel, it’s “Piano Man.” Paul McCartney always receives requests for “Yesterday.”

Lisa Kudrow?

She gets “Smelly Cat.”

At the Rock a Little Feed a Lot benefit concert for Feeding America, the nation’s largest domestic hunger-relief charity, at Club Nokia in Los Angeles Tuesday night, Kudrow, 46, took to the stage with longtime pal and onetime costar Courteney Cox Arquette to introduce singer Sheryl Crow – only to find herself with a guitar thrust upon her and the crowd chanting for her to play the magnum opus of Phoebe Buffay, the ditzy musician she played on Friends.

“Play ‘Smelly Cat!’ ” an audience member called out, after Kudrow and Cox Arquette were pressed into a question-and-answer session while Crow and her bandmates set up backstage.

Kudrow looked to her friend for help, but Cox Arquette gleefully threw her pal under the Benefit bus, calling out to the stagehands: “Get her a guitar, people!”

After being fitted with an acoustic guitar, the momentarily bewildered actress warily asked, “Is this a set up?” before summoning her inner Phoebe and serenading the audience with her ballad about an odiferous feline.

“Smelly cat, smelly cat, what are they feeding you?” she sang.

And the crowd leapt to its feet.

Feeding America announced today that Miley Cyrus, Courteney Cox, Lisa Kudrow, Marcia Cross, Lance Bass, Alison Sweeney, Christina Applegate, OneRepublic and Rob Thomas have joined Sheryl Crow, Ben Harper, Joel & Benji Madden, Jonny Lang and Tom Morello in the fight against hunger and to participate in the “Rock a Little, Feed a Lot” benefit concert on September 29th in Los Angeles. September is Hunger Action Month and the star studded benefit is being held to help raise awareness and funds for the 35 million people who are at risk of hunger in America. Tickets for “Rock a Little, Feed a Lot” are on sale now at www.ticketmaster.com.

Miley Cyrus, Rob Thomas and OneRepublic have pre-taped special performances that will be aired during the concert. Courteney Cox, Lisa Kudrow, Marcia Cross, Lance Bass, Jeff Probst, Alison Sweeney and Christina Applegate will be presenters during the concert. Legendary comedian Garry Shandling will perform a stand up comedy skit.

“It is so important for everyone across the country to dare to be conscious and aware of the struggles of those around them — even if those struggles are not the same as their own. Feeding America does just that, and it’s a great privilege for me to unite with them in their cause,” said Crow.

Adam Shankman, producer and director of “Step Up,” “Hairspray,” “Bringing Down the House,” and “17 Again” is directing the event. Proceeds of the concert will go to the Los Angeles Regional Foodbank and Feeding America.
