Add Tab to a TabPane JavaFX

I am trying to add a new tab with fxml.

I already add tabs to the tabPane.

int numTabs = tabPane.getTabs().size();
Tab tab = new Tab("Tab " + (numTabs + 1));
tabPane.getTabs().add(tab);

But I can't load the FXML to it with 

tabPane.getTabs().addAll((Tab)FXMLLoader.load(this.getClass().getResource("tab.fxml")));`

Error: javafx.fxml.LoadException:

enter image description here

tab.fxml:

<TabPane fx:id="tabPane" layoutX="14.0" layoutY="105.0"
         prefHeight="200.0" prefWidth="292.0" tabClosingPolicy="UNAVAILABLE">
  <tabs>
    <Tab text="Untitled Tab">
      <content>
        <AnchorPane id="Content" minHeight="0.0" minWidth="0.0" prefHeight="180.0" prefWidth="200.0">
          <children>
            <Button layoutX="118.0" layoutY="74.0" mnemonicParsing="false" text="Button" />
          </children>
        </AnchorPane>
      </content>
    </Tab>
  </tabs>
</TabPane>

Edit: I've tried remove de <TabPane> tag but didn't work.
