Who Is Goop's Biggest Fan? Gwyneth Paltrow's 9-Year-Old Son Moses Martin

Little kids love Goop!

Gwyneth Paltrow got a very sweet Mother's Day gift from her son Moses (or "Momo" as he signed): a letter praising her skills as a bunny-owner and a website magnate.

"Thank you for teaching me how to start a website," the letter reads. "I love your website and I wanted to start one, too."

Goop: an aspirational website for grown ups and children alike!

Moses, 9, and his sister Apple, who will turn 11 this week, recently spent a divorce-aversary trip with their parents, Paltrow and Chris Martin, in Mexico. Consciously uncoupled or not, this family stays sweet. Bunnies and all.
