Oh my Gaga! Forbes has released their annual Celebrity Top 100 List, highlighting the world’s most powerful celebrities. In taking the number one spot, Lady Gaga has ousted Oprah from her spot and taken the thrown as Mother Monster. I guess Beyonce was talking about Gaga, when she was says “Girls…who run this mother…”. Collectively, the famous faces that make up the Top 100 earned $4.5 billion over the last 12 months, through, music, film & television, sports, modeling, and more.

So we all know that Gaga’s famous, but how did she earn the top spot? Well, aside from the $90 million she earned last year, she’s been owning the social networking scene with 32 million fans on Facebook and 10 million monsters following her on Twitter. Gaga sold one million digital downloads of her single “Born This Way” in only 5 days! This busy Lady also has her paws in MAC makeup, Monster headphones, and Virgin Mobile phones which she has featured in her music videos.

Oprah, who is in the process of ending her 25 year show with a bang, made $290 million last year, but falls a tad short in comparison to Gaga’s influence on the web and with youngsters.

Check out the Top 10 List below!

Any surprises? For the Top 10, I didn’t expect Bon Jovi to be there, but apparently I’ve been living under a rock (without the roll). In the past 12 months, he’s actually made more than Kanye West, Justin Bieber and Katy Perry combined! Someone’s Living On A Prayer!
