The hotter than hot trio have their fans to thank for the appearance.

The JONAS BROTHERS are making an appearance on "The OPRAH WINFREY Show" on Thursday, and they have their huge fan base to thank for it!

The pop trio first gained popularity by performing with "Hannah Montana" star MILEY CYRUS on her "Best of Both Worlds" tour. Their devoted fans got Oprah's attention by sending nearly 5,000 e-mail requests to her show staff, along with petitions and posting videos on YouTube and other Web sites.

Oprah tells the handsome brothers, "I received thousands of e-mails from your fans begging, pleading to have you guys here -- the most for any guest this year. They barraged us."

So how do they keep grounded given their fervent following? KEVIN JONAS tells Oprah, "It really is our parents and what they kind of seared into our hearts; we've kind of grown up with the saying, 'Even if you're at the top, live like you're at the bottom.'" Adds NICK JONAS, "They don't let it go to our heads, and we've always learned to stay humble."
