Usain Bolt is one of the world's most-famous people and a track and field legend.
But Kerron Clement has appeared in a Beyonce music video - so Clement wins.
The American 400m hurdler is the fifth Olympic gold medallist confirmed for the new Nitro athletics series next month in Melbourne.
Clement, who won his event at the Rio Games, will run in the Bolt All-Stars team.
As recently as last month, Clement's team captain admitted to having a long-time crush on Beyonce.
The singer is one of few people to have left the charismatic Jamaican admitting he was lost for words when they met.
Clement is also an actor and model, who eight years ago featured in the Beyonce video Run The World (Girls).
"To this day, people still talk about it. It's something that I love to do, being in entertainment, in whichever capacity," Clement said.
"Modelling for Sean John, acting in Young and the Restless, well actually it was a small cameo - and even photographing agency models.
"I dabble in photography as well... I'm a man of many skills."
But it is on the track where Clement has made his biggest mark.
He is the world indoor record holder for the 400m and won gold at the Beijing Olympics in the 4x400m relay, as well as silver in the 400m hurdles.
The 31-year-old is a four-time world champion, two apiece in the hurdles and relay.
But after a year of injuries, winning the Rio gold medal was particularly special.
"Not saying I don't value and appreciate my efforts, but it was something about the journey leading up to 2016 summer Games," he said.
"Having dealt with many setbacks and injuries, and having to hit the refocus button and perform at the highest level possible while being under pressure - not many athletes can handle such pressure.
"That's why it means so much to me to win and finally add that elusive gold to my collection."
Bolt's talent-packed Nitro team also features fellow Jamaican Olympic gold medallists Asafa Powell and Michael Frater, along with 2008 Olympic hurdles champion Dawn Harper-Nelson from the United States.
