I can remember when I was 23 years old, the only thing I could say with any certainty is "you want fries with that?"

If I had just paid better attention to my elementary school music teacher, I too would a rich and famous country music singer, NOT!

The list of top earners was just released. Country's biggest stars Taylor Swift and Carrie Underwood are on the top end of the list.

According to Forbes list of “Best Paid Celebrities Under 30” include Swift and Underwood, but neither is at the top of the list.

The number one slot belongs to a pop star Lady Gaga who earned an estimated $90 million.

Seventeen-year-old Justin Bieber lands at No. 2 with $53 million.

NBA star LeBron James is at No. 3 with $48 million, followed by tennis champ Roger Federer at No. 4 ($47 million), Taylor Swift at No. 5. earning over $45 million and her live shows bring in $750 thousand dollars a night. All the while Carrie Underwood only collected a measly $15 million.

Other celebrities on the list include Katy Perry earning $44 million, soccer player Cristiano Ronaldo he made $38 million, bouncy booty Beyonce shook in $35 million, and Rihanna sang herself to the $29 million dollar mark.

What I wouldn't give for the chance at the big time, but that would mean getting on a stage and singing. OK never mind.
