Justin Bieber looked like he was having a great time in Victoria’s Secret on Monday night. The 20-year-old singer went to the store, and then decided to mock his Calvin Klein ads on Instagram. Last month, Celebuzz showed the public Bieber’s Calvin Klein underwear ads. The photos were everywhere, and everyone was talking about them. Miley Cyrus even decided to parody his ad on Instagram. Now, it seems like Bieber is laughing at himself after posting a new photo to Instagram with the caption, “#mycalvins.” From his Instagram photos, it looks like Bieber was walking around the mall. Just a casual Monday in the world of Bieber.
