How do i use include() with two relations?

CustomerSupplier has CustomerId and CustomerAddressId the relation matches the field in the table CustomerAddress.

Table:CustomerSupplier
CustomerId
AddressId
SupplierId
ServiceName
…

Table:CustomerAddress
CustomerId
AddressId
Location
…

Im looking for something link this:

`var CustomerSupplier = db.CustomerSupplier

       .Include(x => x.CustomerAddress.CustomerId)
       .Include(x => x.CustomerAddress.AddressId) // This doesn't work

`
