As Usain Bolt is pictured in bed with another woman, we look at the other celebs who got caught in the act
THERE'S no denying it when you're caught on camera
RULE number one of cheating (apart from not to do it in the first place) is don't get caught - especially if you're famous.
But some celebrities who struggle to keep it in their pants are also pretty careless when it comes to covering up their tracks.
This week Olympic athlete Usain Bolt was photographed in bed with 20-year-old student Jady Duarte, despite being in a committed relationship with Kasi Bennett.
While he has kept schtum about the pictures, Duarte claims the pair spent the night together after he celebrated his 30th birthday.
"I'm dying of shame," she has since admitted.
Here, we look at other celebs who got caught on camera...
Zayn Malik
While he was in a relationship with Perrie Edwards, Zayn Malik found himself in hot water when Courtney Webb took photos of him sleeping next to her.
She claimed to have slept with the former One Direction star after meeting at London nightclub DSTRKT and heading back to his flash London pad.
Although the Little Mix star forgave him, he was later pictured in a close embrace with a fan and their relationship ended soon afterwards.
Robin Thicke
The singer made the most of his success in 2014 by getting up close and personal with countless women.
Seeming to forget he was married to Paula Patton, Robin was pictured kissing a mystery woman in a Paris nightclub.
He also made the error of grabbing a fan's derriere while they posed for a snap together, but when she uploaded it to Instagram people quickly spotted the mirror behind them - including Paula, presumably.
Soon after the evidence surfaced, she filed for divorce.
Scott Disick
You'd think being in a relationship with a Kardashian would keep the self-confessed Lord satisfied, but even Kourtney couldn't stop him from straying.
He was pictured looking very cosy with stylist Chloe Bartoli during a holiday in France and when the mother of his three children Mason, Penelope and Reign spotted the photos, she dumped him.
Serves him right!
Zoe Ball
In one of the most surprising celebrity hook-ups, the TV presenter suffered the embarrassing mistake of snogging Franklin Lake singer TayTay Starhz after a few too many G&Ts.
But the worst was yet to come when the pictures surfaced of the unlikely pair locking lips.
Zoe's spokesperson claimed the snog was "completely meaningless" and luckily her husband PJ Norman let it go.
Phew!
Kristen Stewart
Most women would kill to be on the arm of Robbert Pattinson, but Kristen Stewart strayed during their relationship.
The actress was pictured kissing her Snow White and the Huntsman director Rupert Sanders, who incidentally was married too.
After the pictures were splashed all over the papers, she released a statement that said, "This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry."
They reconciled, but split the following year.
