Internet pranksters and semi-naked attenders of awards ceremonies The Janoskians have criticised One Direction's Louis Tomlinson for having a baby with Brianna Jungwirth.
The fivesome, who have previously tried to spark jokey feuds with 1D, let loose on Louis - with Jai Brooks from the band saying he "should have worn a condom".
Speaking to The Dish in a surprisingly eloquent manner, he said: "You have really got to think about the responsibilities and consequences of your actions; at least I have been safe and I have been doing that my whole time as part of The Janoskians. I really think of the consequences before I do anything."

Jai's brother Beau agreed, saying Louis might be "haunted for life" by getting Briana pregnant. He added in a less eloquent manner: "When it's raining, just wear a raincoat."
The Janoskians are composed of Jay, Beau and Luke, as well as siblings Daniel and James Sahyounie. The band have had run-ins with One Direction in the past, previously claiming they had 'ripped off' one of their songs.
However, the bands are now on fairly decent terms, as The Janoskians presented 1D with the Choice Hottie gong at the Teen Awards.
Beau finished by saying: "One mistake can haunt you for the rest of your life. Be safe and make sure you know that every decision you make is the right one."
That's actually pretty good life advice for someone that makes a living from throwing up on camera. The boys are currently promoting their tour DVD Untold And Untrue, which charts their journey to playing Wembley.
