Singer Justin Bieber has got an apology from BreatheHeavy.com over his Calvin Klein photographs after he threatened to take legal action if his photoshopped images are not deleted by the website.

Earlier, the website claimed that `someone connected` to the 20-year-old's Calvin Klein photo shoot emailed them a picture before it was altered.

Now, BreatheHeavy.com has posted a retraction and apology which reads: `Hello new and old BreatheHeavy.com readers! Team Bieber sent BreatheHeavy a cease and desist letter because of the alleged un-retouched Calvin Klein photo we posted, asking we remove the picture in question as well as provide a retraction,` reports aceshowbiz.com.

The site added: `Because BreatheHeavy is not about making anyone feel bad or intentionally stirring the pot (and are definitely not here for lawsuits), we shall retract the story per request. Bieber denies the photo is real, and I respect that and will believe him.`

The site posted a quote from Justin's trainer Patrick Nilsson defending Bieber.

`I can definitely confirm that (Justin) is a well-endowed guy. I sound weird saying that, but yes," Patrick told Access Hollywood.

It also shared Calvin Klein's comments to Us Weekly magazine about the 20-year-old's behaviour during the photoshoot, which reads: `Justin showed up early every day with amazing energy; he completely trusted us and gave it his all... He came alive when it was time to perform, especially when the drum kit came out - it was really impressive.`

BreatheHeavy.com added: `No harm, no foul. We sincerely apologize to Bieber for the hit to his ego and to the millions of tweens on social media we upset: Swag swag swag, on you. Chillin' by the fire while we eatin' fondue.`
