Scruffy Ryan Seacrest reveals his toned tummy during sweaty jog in Rio while Instagram fans warn him of Zika virus
Ryan Seacrest arrived in Rio de Janeiro just days ago as he is set to host Friday's Olympic opening ceremony.
But the 41-year-old television host - who is typically polished to perfection - opted for casual wear while jogging in Brazil.
Seacrest's Instagram fans have warned him to be careful of the Zika outbreak, which has swept through the South American country more than any other.

'Don't get Zika': Ryan Seacrest looked less than polished while jogging in Rio de Janeiro on Wednesday as his social media fans warned him of the virus
'Don't get zika' and 'wear a lot of mosquito repellent' are a few of the messages posted to the former American Idol host's account.
The Zika virus is spread by mosquitoes and can lead to Guillain-Barré syndrome - which can cause muscle weakness, paralysis and even death.
He sported a bit of scruff as he stepped out for a run in the ritzy Ipanema neighbourhood.

Seacrest stood on the beach and captioned the image: 'Competition just started here in Rio! 3 days til my own games begin on @nbcolympics late night.'
He will be joined by Victoria's Secret Angel Brazilian babes Alessandra Ambrosio and Adriana Lima - who will act as special correspondents.
The trio toured Rio's culinary hot spots for a segment, with stops including the steakhouse Fogo de Chão and a famous café called the Confeitaria Colombo.
On Tuesday, 'Ale' posted an Instagram photo of the tour's culmination: a poolside cocktail hour at the luxurious Belmond Copacabana Palace.
