UIImageView image is stretching when i am using rounded corners.

I am using UITableViewCell as UITableView Header. I am using the below code to make rounded corners for UIImageView.

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    if(section==0){

    static NSString *simpleTableIdentifier = @"ContactDetailsHeaderTableViewCell";

    ContactDetailsHeaderTableViewCell *cell = (ContactDetailsHeaderTableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];


    if (cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ContactDetailsHeaderTableViewCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];

    }

    ..................
    .................

UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];

        //rounded corners
        cell.profilePicImgView.clipsToBounds = YES;

        UIGraphicsBeginImageContextWithOptions(cell.profilePicImgView.bounds.size, NO, 1.0);

        // Add a clip before drawing anything, in the shape of an rounded rect
        [[UIBezierPath bezierPathWithRoundedRect:cell.profilePicImgView.bounds
                                    cornerRadius:60.0] addClip];
        // Draw your image
        [img drawInRect:cell.profilePicImgView.bounds];

        // Get the image, here setting the UIImageView image
        cell.profilePicImgView.image = UIGraphicsGetImageFromCurrentImageContext();

        // end drawing
        UIGraphicsEndImageContext();


.............
.............
}

Below is the output

The image inside the UIImageView is stretching, if i am not using the rounded corners then the image is looking properly. I have tried lot of code sample from StackOverflow but none of them are working.
