CakePHP 2 sends out 2 emails each time - email

Question

I've come across a strange error in CakePHP when sending a contact form to a recipient via e-mail. When a contact form is filled out and is submitted, CakePHP then sends the e-mail to recipient absolutely fine. But instead of sending one email once it seems to send two emails at the same time.
My controller code is this:
var $helpers = array('Html', 'Form', 'Js');
var $components = array('Email', 'Session');
public function index() {
$this->layout = 'modal';
if(isset($this->data['Contact'])) {
$userName = $this->data['Contact']['yourname'];
$userPhone = $this->data['Contact']['yourtelephone'];
$userEmail = $this->data['Contact']['youremail'];
$userMessage = $this->data['Contact']['yourquestion'];
$email = new CakeEmail();
$email->viewVars(array(
'userName' => $userName,
'userPhone' => $userPhone,
'userEmail' => $userEmail,
'userMessage' => $userMessage
));
$email->subject(''.$userName.' has asked a question from the website');
$email->template('expert', 'standard')
->emailFormat('html')
->to('recipient-email#gmail.com')
->from('postman#website.co.uk', 'The Postman')
->send();
if ($email->send($userMessage)) {
$this->Session->setFlash('Thank you for contacting us');
}
else {
$this->Session->setFlash('Mail Not Sent');
}
}
}
And this is the code for the contact form:
<?php
echo $this->Form->create('Contact', array('url' => '/contact/ask-the-expert/', 'class' => 'contact'));
echo $this->Form->input('yourname', array(
'type' => 'text',
'label' => 'Your Name <span class="star">*</span>',
));
echo $this->Form->input('yourtelephone', array(
'type' => 'text',
'label' => 'Your Telephone',
));
echo $this->Form->input('youremail', array(
'type' => 'text',
'label' => 'Your Email <span class="star">*</span>',
));
echo $this->Form->input('yourquestionAnd ', array(
'type' => 'textarea',
'label' => 'Your Question <span class="star">*</span>',
));
echo $this->Form->submit();
echo $this->Form->end();
?>
Cheers!

Put your Mail Send code inside if ($this->request->is('post')) {} and try.
UPDATE
updated the code.
var $helpers = array('Html', 'Form', 'Js');
var $components = array('Email', 'Session');
public function index() {
$this->layout = 'modal';
if(isset($this->data['Contact'])) {
$userName = $this->data['Contact']['yourname'];
$userPhone = $this->data['Contact']['yourtelephone'];
$userEmail = $this->data['Contact']['youremail'];
$userMessage = $this->data['Contact']['yourquestion'];
$email = new CakeEmail();
$email->viewVars(array(
'userName' => $userName,
'userPhone' => $userPhone,
'userEmail' => $userEmail,
'userMessage' => $userMessage
));
$email->subject(''.$userName.' has asked a question from the website');
$email->template('expert', 'standard')
->emailFormat('html')
->to('recipient-email#gmail.com')
->from('postman#website.co.uk', 'The Postman')
if ($email->send($userMessage)) {
$this->Session->setFlash('Thank you for contacting us');
}
else {
$this->Session->setFlash('Mail Not Sent');
}
}
}
