Since the Justin Bieber bare-it-all episode on Monday night on Instagram, the Internet became rife with the same trend of people showing their behind.

This time, Christy Teigen jumped on the bandwagon. She posted a photo of hubby John Legend's backside birthday suit, exhibiting the singers butt, according to Billboard.

For her endearing antics, the beautiful and outspoken model has considerable followers on social media. Teigen has been in an online crusade to defy Instagram on their photo-sharing policy. This is because whenever she posted a picture with her nip showing, Instagram would remove it, and she would then repost.

It is up to Instagram how long they would allow John Legend's behind to float around before they remove it.

People reported that this is also Teigen's response to a "certain male pop star" who exhibited his butt on Instagram.

The photo showed at least two-thirds of Legend's buttocks.Teigen posted it without any caption, but the photo itself speaks a thousand words.

Chrissy Teigen and John Legend are set to celebrate their second wedding anniversary this September. Recently, the couple graced the Armani show during Paris Haute Couture Fashion Week in Paris on Tuesday.

Teigen looked stunning in her gray top and cream trousers as she was escorted by hubby John. She accented her long-sleeved outfit with high flares and a baby-blue clutch bag. She complemented her overall getup with a necklace made of colorful stones and a pair of tortoiseshell sunglasses, reported Daily Mail.

Bustle recounted how the couple met: Teigen, then still making a name for herself as a model, was cast for Legend's music video for the song "Stereo" in 2007. They dated for four years before getting engaged in 2011. They tied the knot in September 2013.

Teigen is the inspiration for Legend's heartwarming hit "All of Me."
