Justin Bieber and an unlikely pal, Ozzy Osbourne, teamed up earlier this month to film a futuristic Super Bowl ad for Best Buy – and, so far, the details are top secret.

On Jan. 17, when the shoot took place, Bieber, 16, told his 7 million Twitter followers, "Can't really say what I'm up to today but when u guys find out its gonna be funny as heck," later adding, "#todaywasepic." Then on Wednesday, he spilled the beans a bit, admitting to filming a "pretty funny commercial" with Osbourne, 62.

For his part, the Prince of Darkness has kept his lips sealed, as has his wife, Sharon Osbourne, who was also present for the shoot. According to USA Today, the 30-second ad, which will air in the third quarter, is Best Buy's first-ever Super Bowl commercial – and from the looks of it, it's bound to leave an impression! – Kate Hogan
