Listing all open workbooks except Current within combobox vba

Question

I am currently using this code to list all open workbooks within a combobox, but I don't need the source workbook to be listed as well.

Dim wkb as Workbook
With Me.ComboBox1
For each wkb In Application.Workbooks
.Additem wkb.name
Next wkb
End with

Tried .removeitem 0 But it identifies source workbook as item 0, only if it has been opened before all other workbooks.
