ANTHONY JOSHUA'S 30th birthday celebrations were gatecrashed by drug testers – just as he was about to tuck into a massive chocolate cake.
The British star, 30, is gearing up for his rematch with Andy Ruiz Jr in Saudi Arabia on December 7.

Even when celebrating his big 3-0 he couldn't escape his pre-fight preparations, as his day was ruined by a surprise drug test.
In a video shared on social media, Joshua's pals can be seen bringing out a humongous cake – only for the doping testers to arrive.
Joshua was forced to give a blood sample – and probably didn't have any cake either.
The Watford boxer has massively trimmed down in recent weeks as he looks to become quicker and more mobile – shedding plenty of muscle mass in the process.
Joshua lost his first-ever professional fight to Ruiz in June, in one of the sport's biggest shocks – and is set to more than DOUBLE his net worth from the upcoming rematch.
And fans are thrilled that he looks "more like a boxer than a bodybuilder" now as he looks to exact revenge.
NO INSTA POSER
One fan said: "Joshua looks a lot better now he's shedded the weight. Like he just wanted to pose for Instagram before."
A fellow user wrote: "Yes AJ. The 2014/15 lean, mean, hook-wielding, uppercut-throwing machine is back by the looks of things."
Another commented: "Anthony Joshua cutting plenty of weight for his rematch with Andy Ruiz Jr is absolutely what's needed."
A fellow user posted: "AJ appears to have lost some muscle mass which is great, he was better when not as big."
Another wrote: "AJ was way too heavy for the first fight. This time he's already shaved all that muscle off. Light work this time, he's going to ruin Ruiz."
But Ruiz too has shed the pounds, swapping Snickers bars for avocado and working on his core, cardio and speed in the gym.

Speaking of his transformation, Ruiz said: "I think it will be a hard fight, but nothing is easy in life, so we are training very hard. We will be prepared for whatever he bring.
"I will arrive in better condition…. lighter, faster and more powerful. They will believe that in December they will win.
"People will always talk like this, but I have faith that we're going to win and shut up more mouths."
