Poor Dan!

Celebrity Big Brother star Dan Osborne has revealed a nasty-looking injury on Instagram today.

The former TOWIE star is known for his dedication to the gym, even creating his own fitness empire helping to train the likes of Daniel Armstrong and Ferne McCann.

But it looks like 27-year-old Dan might have taken his exercise regime a little too far this time, as he’s now managed to damaged his bicep.

Taking to his social media page, the dad-of-three can be seen sitting in his car with a sling around his neck, next to the caption: ‘Torn bicep,’ and a thumbs up emoji. Ouch!

While the reality star – who shares kids Ella, four, and one-year-old Mia with wife Jacqueline Jossa, as well as five-year-old Teddy from a previous relationship – didn’t specify how he managed to injure himself, we reckon the gym had something to do with it.

Meanwhile, Dan’s latest Insta post comes just days after he celebrated eldest daughter Ella’s fourth birthday with the rest of his family.

Giving a glimpse into the lavish bday bash, former EastEnders star Jacqueline shared a string of videos showing a wall of roses, face painting station and even a giant unicorn cake.
