As the Comedy Central Roast of the love-him-or-hate-him tween idol is about to air next Tuesday, it seems like the relationship between Justin Bieber and Selena Gomez wasn't only the butt of a good number of the jokes, but there was also some inside scoop, as the young actress and singer actually gave advice on how to roast Bieber!

The Justin Bieber and Selena Gomez has been the subject of tabloid love for the past four years, as they've been on and off over again throughout this time, and most recently the "Spring Breakers" star released a hit song supposedly about their relationship, the heartfelt tune "The Heart Wants What It Wants," which she introduced at the AMAs.

It's said that you only roast the ones you love, but the previews and reviews show that there wasn't so much love for the "Baby" singer in the Comedy Central panel at the time of the show - but Jeff Ross made sure to get the opinion of at least one person who's cared about the singer, following the rocky Justin Bieber and Selena Gomez relationship.

According to The Inquisitr, Jeff Ross, who is known as The Roastmaster General due to his appearances and incredible insults in the Comedy Central show, asked the 22 year-old singer and Bieber ex for her advice before the roast, so he could write jokes based on truth.

And being only too supportive in the name of good fun (and perhaps of burning an ex), the actress was only too happy to comply, giving Ross material about the Justin Bieber and Selena Gomez relationship.

The revelation was made when Ross recently did an interview with The Huffington Post, as he was asked about his years' experience in the Comedy Central famous show and whether he did any research on his subjects before writing the jokes - and he then confessed he'd talked to Selena, who told him to tell the truth because that always worked for her.

There will be many Justin Bieber and Selena Gomez in the Comedy Central Roast, which will air next Tuesday, March 31.
