The 53rd Annual Grammy Awards ceremony has not even officially begun, but with over 100 categories being recognized this year — from Best New Artist to Best Improvised Jazz Solo — there's simply not enough time to squeeze everything into the three-hour telecast.

That's why a slew of awards have already been handed out. Preshow winners include Lady Gaga, Rihanna, Jay-Z, Bruno Mars, the Black Keys and more.

Gaga, who is nominated in six categories, now has a Best Female Pop Vocal Performance win for "Bad Romance," after besting Beyoncé ("Halo") and Katy Perry ("Teenage Dream"). But the pop star, who became the talk of the red carpet when she showed up encased in a huge, translucent egg, also fell short in two early categories: Her duet with Beyoncé, "Telephone," lost out for Best Pop Collaboration With Vocals to Herbie Hancock, Pink and friends' "Imagine," while Rihanna's "Only Girl (In the World)" nabbed Best Dance Recording over Gaga's "Dance in the Dark."

The win for Rihanna marks an auspicious return to the Grammys ahead of her upcoming performance with Drake and Eminem. Yet she, too, has already fallen short in a few categories: Jay-Z and Alicia Keys took home both Best Rap Song and Best Rap/Sung Collaboration for "Empire State of Mind," twice beating out RiRi and Em's "Love the Way You Lie." Jay also picked up a win for Best Rap Performance by a Duo or Group, along with Swizz Beatz, for "On to the Next One."

In the Rock categories, the Black Keys garnered a win for Performance by a Duo or Group With Vocals ("Tighten Up"), prevailing over the likes of Arcade Fire ("Ready to Start") and Kings of Leon ("Radioactive").

In the world of pop, Bruno Mars came out on top for Male Pop Vocal Performance ("Just the Way You Are"), defeating Michael Jackson ("This Is It"), John Mayer ("Half of My Heart") and others.
