He plays bass and provides vocals for the popular band "Fall Out Boy," not to mention being married to one of the most closely watched celebs on the paparazzi circuit - Ashlee Simpson.
Born in 1979, the American showed his rebellious attitude from an early age. He was regularly getting himself into trouble at school and even had to be sent to boot camp by his parents in an effort to straighten him out.
As an outlet to his frustration, Wentz began writing songs and playing the bass guitar.
Before his part in "Fall Out Boy", Wentz was a member of several bands including First Born, Extinction and Arma Angelus - all punk rock bands.
While Wentz is an integral part of his current band, the singer has also branched out into other areas of business.
Wentz is currently involved in a number of bars and nightclubs in the U.S. and has even had his foot in the fashion industry.
More notably, Wentz is currently a campaigner with the United Nations and is helping to raise awareness about the importance of providing safe drinking water to young children.
The UNICEF Tap Project encourages people to donate just $1 for tap water at U.S. restaurants during World Water Water Week.

Israel's mayor of Jerusalem, Nir Barkat, is charged with running arguably the world’s most contentious and disputed city.

A father of three and former paratrooper, Barkat suspended his extensive portfolio of interests in high-tech business to enter politics in 2003.
Following his election as mayor in November 2008, Barkat was the hope of the city’s secular Jewish community and a change from the Jewish orthodox leadership of his predecessor, Rabbi Uri Lupolianski.
Barkat inherited a city with a number of problems. Jerusalem is one of the region's poorest cities, and faces a range of other problems: job shortages, soaring house prices, not to mention ongoing religious tensions over sites such as the Al-Aqsa Mosque.
Further to this, Jerusalem’s role as Israel’s capital is disputed by some countries, while the status of east Jerusalem in any peace agreement with the Palestinians is increasingly contentious.
Jerusalem’s status in any peace negotiations with the Palestinians has been an ongoing source of controversy.
He left the centrist Kadima party over their willingness to include Jerusalem in any negotiations and has continued to declare his desire to build more Jewish homes in Palestinian and Israeli-Arab areas in the east of the city, occupied by Israel in 1967.
This is your chance to put a question to Nir Barkat - a man with the potential to play a crucial role in the Middle East peace process.

"Samson and Delilah" is a brutally realistic depiction of the plight of two teenagers growing up in central Australia’s indigenous communities.
They fall in love and despite the challenges of poverty, violence, drugs and sexual abuse, they manage to survive.
Thornton, an Aboriginal filmmaker based in Alice Springs, aims to humanize his people through his film and open the eyes of mainstream Australia to their struggle.
"I grew up in Alice Springs and I spent most of my childhood on the streets at night. Everything in that film I have witnessed."
Thornton cast untrained actors in all the lead roles in order to utilize their own firsthand experiences.
"Most 14-year-olds in Alice Springs are walking around with the knowledge of a 90-year-old, from what they've experienced. They're bullet-proof."
The film was produced on a budget of less than $.15 million - a fraction of the average Hollywood budget - but it has gone on to win international acclaim, such as the Caméra d’Or at Cannes in 2009.
Here’s your chance to put your questions to Warwick Thornton.
Do you think his film will help bridge the gap between White Australia and the Aborigines? Has Prime Minister Kevin Rudd's apology to Aboriginals helped?
