Selena Gomez mentioned that watching Justin Bieber's "Believe" film would be "way too painful for her," HollywoodLife.com reports, leaving many wondering if she's ignoring his Twitter account, where he constantly promotes his film.

"I'm sure Selena will be tempted to watch Justin's movie but it would be way too painful for her at this point," a source tells HollywoodLife.com

"She's trying to put her focus anywhere but on Justin. She's not over their breakup so watching his movie would just be torture for her."

Justin Bieber has been focusing his Twitter posts on the countdown to the release of his "Believe" movie and mentioned during a radio interview that he's retiring.

In a short video clip filmed during an interview at the Power 106 station Tuesday morning, he says, "Um, I'm actually retiring, man," EOnline.com reports.

His reps had no comment, but a source told E! News, "Of course it's not true," the website also reports.

Justin Bieber released a sneak peak of his "Believe" trailer and some say it discusses his love and subsequent break up with ex-girlfriend Selena Gomez.

When asked if he's ever been in love, he softly replies, "Of course I've been in love. I think being in love is the most powerful thing," HollywoodLife.com writes.
