The actress, 51, along with Jennifer Lopez, backed her photographer pal Mark Seliger's decision to auction off the naked portrait on Instagram this week.
Jennifer isn't the only star to have their portraits auctioned off for charity as other shots also include Leonardo DiCaprio, Dr Dre, Snoop Dogg and Billie Eilish to name a few.
Notably a Jennifer Lopez 2001 portrait by Seliger features in the auction.
