The baby’s sex and name were not known until now, but a message of congratulations from a woman who claims to work at Westchester Medical Center seems to have let the details slip.
The message from @kimbanksy read: ‘Congrats @blakelively #blakelively glad to have you and baby girl violet in our care.

The tweet, first picked up by Page Six, could not be immediately verified. MailOnline reached out to Blake’s representative for comment but did not receive an immediate response, yet.
