Sandra Bullock's son Louis is the lucky recipient of a $14,000 Andy Warhol painting.

The gift, Warhol's classic Peaches painting, was purchased by Bullock's agents, Us Weekly reports.

The purchase was made at the annual American Foundation for AIDS Research (amfAR) Inspiration Gala, held at the Chateau Marmont in Los Angeles on Thursday.

I want to thank Kevin Huvane and Bryan Lourd for not being cheap f-cks and gifting my son with his first Warhol, Bullock said.

Bullock and other Hollywood stars, including Josh Duhamel, Rose McGowan and singer Debbie Harry showed up to the event to honor the late Elizabeth Taylor, who passed away in March.

Since 1985, when Taylor co-founded amfAR, the organization has raised more than $325 million in support of research and related programs.

Earlier this year, the world lost a radiant woman of courage and compassion. She lives on in every person she touched . . . she never thought twice to put her arm around someone who was suffering, and that is the gift we have as human beings, the ability to reach out and touch another human being, Bullock said at the gala.

In April 2010, Bullock announced that she had adopted baby Louis, a three-and-a-half month old boy from New Orleans.

He's just perfect, I can't even describe him any other way . . . it's like he's always been part of our lives, she told People at the time.

Bullock, 47, recently finished filming the big screen adaptation of Extremely Loud and Incredibly Close, the bestseller by Jonathan Safran Foer. The film, out Jan. 20, 2012, also stars Tom Hanks, James Gandolfini and Viola Davis.
