Basically what the title says.

It's unclear throughout TCW if Ahsoka ever knew about Anakin and Padme. It's very likely that, since Anakin had told Rex about Padme in season 7, Anakin was going to tell Ahsoka but was never able to. Since she's so young throughout TCW, it's never clear if she picks up on Anakin and Padme's relationship.

Ahsoka never interacts with Padme in season 7. But at Padme's funeral, her body was made to still appear pregnant. So - did Ahsoka ever know that Padme was pregnant? If she did, she'd probably have a guess as to the father.
