Lady Gaga
At only 25, Lady Gaga is on the road to becoming a billionaire Reuters

Lady Gaga is one of the richest people in the world. The Born this Way singer earned $62 million in 2009, and since May 2010 she has brought in $90 million, according to Forbes - who put her earning potential for 2011 at over $100 million.

These numbers contribute to a net worth of $110 million.

Between her extravagant wardrobe choices, unconventional music videos and elaborate world tours, it's no surprise that Lady Gaga had made an impression even beyond the music industry - which has in turn made a considerable impression on her bank account.

Gaga's massive appeal is reflected not only in her 15 million-plus record sales for The Fame and Fame Monster and five Grammy wins. She is the number one most followed person on Twitter, with over 11 million followers. Her partnership with Mac Cosmetics and endorsement deal with Virgin Mobile have helped grow Lady Gaga's public persona as well as her personal wealth. Within the course of a year, Lady Gaga has grossed $170 million on her world tours.

Gaga's charitable efforts are likewise lucrative. By lending her name to promote fundraising and relief efforts, Lady Gaga helped raise $2 million for victims of the Haiti earthquake and the Japan tsunami.
