Justin Bieber was the topic of conversation this week due to nude photos surfacing online from his vacation in Bora Bora, but his dad, Jeremy Bieber, just made that a little more awkward.

In a tweet he has since deleted, the 21-year-old “What Do You Mean?” singer’s dad referenced his son being well-endowed and included a blush face emoji.

"@justinbieber what do you feed that thing. #proud daddy," he tweeted on Friday, E! Online reports. He followed up that tweet by calling his son’s penis is a "beaut."

Meanwhile, Bieber has threatened to sue over the nude photos, sending out a cease and desist letter to any publication who published them this week.

The Hollywood Reporter reports his lawyers asked for removal of the photos, writing, “We recently became informed that your company has obtained and is distributing unauthorized photographs of our Client including images showing him without clothing.”

If the photos aren’t taken down in 12 hours, a lawsuit will follow.
