Liv Tyler helped her pal Stella McCartney launch the Stella McCartney boutique at Saks Fifth Avenue in New York this week!  The celeb moms are best friends from way back, Liv and Stella have known each other since they were babies.

Liv Tyler’s mother Bebe Buell and Stella McCartney’s mother Linda were friends and the girls played together as babies!

Liv wore a black peplum dress from Stella McCartney’s Fall 2011 collection to the Saks Boutique launch.  The two moms support each other and Liv Tyler says McCartney is very sweet about gifts for her son Milo.

The British designer, who is the mother of four children, told PEOPLE that Liv sends pictures of Milo wearing McCartney’s kids collection:

“Liv sends me pictures of Milo all the time in my clothes. He’s a beautiful boy, I have to say.”

Liv Tyler, Stella McCartney and their other BFF Kate Hudson are often seen at fashion events, such as the 2010 Costume Institute Gala at The Metropolitan Museum of Art. The “besties” are seen below with friend Kate Bosworth.
