There are 10 celebrities-turned-athletes who have made a name for themselves amongst sports fans.
In recent years, fans have become accustomed to seeing athletes venture into the world of entertainment; the names Terrell Owens, Lamar Odom, Chad Ochocino, and Michael Vick have appeared in TV Guide.
Popular entertainers have also been given the opportunity to show off their athletic prowess (or lack thereof), due to the increased viewership of celebrity athletic events.
From Hollywood Hill to Capitol Hill, here are the top 10 best celebrity athletes.
"Back and better than ever," a phrase that many die-hard sports fans hear at 6 a.m. ET every weekday.
Athletically savvy, he is not.

In 2011, Greenberg—or "Greeny"—enlisted the help of his childhood crush and 18-time Grand Slam winner, Chris Evert.
The pair teamed up for a doubles playoff match, open to public qualifiers.
Midway through, Greenberg added an alternate definition to the term "backstroke".
Arne Duncan, the 48-year-old United States Secretary of Education, is a baller.
A middle-aged, gray-haired passing magician.
Although, it's somewhat expected given his basketball pedigree. Duncan played college basketball at Harvard, even acquiring the title of co-captain during his tenure on the varsity team.
After receiving his diploma in sociology, Duncan traveled to Australia to pursue his professional basketball dreams. For nearly four years, he suited up for the Eastside Spectres of Melbourne.
The St. Louis rapper is no stranger to competition—his skills on the diamond earned an MVP trophy in the St. Louis Amateur Baseball Association.
The lifelong Cardinals fan has won multiple MVP awards at MTV's Rock N' Jock football events (the stats are nonexistent—it's almost as if MTV burned all footage from the Carson Daly era. Understandable.)
In fact, his three mix tapes are entitled: The Come Up, The Warm Up, and Friday Night Lights. His debut album was named, Cole World: The Sideline Story.
His single "I'm On It" was featured in Derrick Rose's Powerade commercial.
However, his moment in the spotlight came in the 2012 NBA All-Star Celebrity Game, when Kevin Hart floated a fast-break alley-oop in the air before Cole slammed it through the cylinder.
He loves to hate it.
He even volunteered to have his torturous golf swing put on public display in Hank Haney's (Tiger Woods' former swing coach) television show.
OK, technically, Rob Dyrdek should be disqualified due to his background as a professional athlete.
Although his pipe dream was lived through a half-pipe, his personality would ultimately be his claim to fame.
At 11 years old, Dyrdek began skateboarding. By his sweet 16, he'd dropped out of high school and booked a flight to Southern California to chase his elusive dream of becoming a professional skateboarder.
Eventually, he would catch it.
Fast-forward a couple of decades later, and Dyrdek has transformed into a household name dripping with MTV fame. His shows Rob and Big and Rob Dyrdek's Fantasy Factory have metamorphosed into multi-season successes.
After training with legendary figure "Rowdy" Roddy Piper, Rob heard the Wrestlemania 27's crowd chant his moniker: "Kid Lightning".
In season four of Fantasy Factory, Dyrdek would jump from skateboarding to wrestling—literally.
If there were no words accompanying this slide, you would probably still spend the most time on it.
Although diamonds are a woman's best friend, they temporarily had a change of heart as Upton strutted onto one in the MLB Celebrity All-Star Game.
Kevin Hart is a 5'2" blur of aggressive, in-your-face, trash-talking fury.
He's called Metta World Peace the "stronger version of Prince", puffed up and nearly thrown a haymaker Shannon Brown's way, made it rain from three against UConn's Lady Huskies, and mocked Shaquille O'Neal's over-dramatic collapses on the court.
He may star in a record-breaking comedy, Laugh at My Pain, but there's nothing remotely funny about his anger problems when he posts in the paint.
Maria Menounos lives for celebrity sporting events.
A Massachusetts native, the 33-year-old is a die-hard Boston sports fan.
Maria Menounos loves sports, and sports fans love her even more.
The Groundhog Day star was once the color commentator during a Cubs broadcast, was asked by director Jeff Santo to partake in the documentary This Old Cub, and popped champagne with the team after the Cubs were crowned the kings of the NL Central in 2007.
One of Murray's earliest roles, Caddyshack, is renowned as one of the best sports movies of all-time.
