Willow Smith and Lady Gaga were digital divas who won big at last night's MTV O Music Awards -- the inaugural awards show celebrating web-savvy recording artists and digital music accomplishments.

Willow, age 10, won Most Viral Dance award for her hit 'Whip My Hair.' Lady Gaga, who holds the record for largest Twitter following (although she's tailed closely by Justin Bieber) won Must-Follow Artist on Twitter. The 'Judas' singer recently lashed out out at hackers for breaking into her Twitter account, threatening to sic her massive fanbase of monsters on the perps.

Gaga, 25, also won an award called Innovative Artist. There's her wild 'Born This Way' video, GagaVision webisodes and her 2011 Grammys entrance in an egg for evidence.

MTV O Music Award Winners were voted by fans online and via social media platforms. The event was seen online Thursday night via live streams from multiple venues in Las Vegas.

Another noteworthy winner was Kanye West, who won Best Tweet. Yeezy's hilarious, winning tweet (from Oct. 2010) reads, "I hate when I'm on a flight and I wake up with a water bottle next to me like oh great now I gotta be responsible for this water bottle."
