Paul Danan had to be physically restrained by his 'Celebrity Big Brother' housemates after he got into a blazing row with fellow competitor Sarah Harding this week.

The former 'Hollyoaks' actor - who is a recovering drug and alcohol addict but has been clean for five years - unleashed a foul-mouthed tirade at the ex-Girls Aloud singer on Thursday (10.08.17), branding her a "f*****g d**k" and a "hypocrite" after she asked if he had had a drink and accused him of "taking a pill."

The argument erupted when 'Real Housewives of Beverly Hills' star Brandi Glanville asked him how he was feeling as he frantically paced around the living room.

He replied: "I'm just trying to get through the non-alcohol thing. I'm just struggling."

Brandi replied: "Well Sarah said you were taking a pill."

Paul, 39, then stormed out into the garden towards Sarah and screeched: "Sarah don't ever insinuate that I'm taking a pill! I'm taking Paracetamol and Ibuprofen."

The blonde star panicked and told the actor to calm down.

But Paul hit back: "No, I'm not going to f*****g calm down. I'm the one that's clean and sober what the f**k are you doing?"

After the pair started to raise their voices, 'Gogglebox' star Sandi pulled Paul away and he raced up to the diary room to talk through his issues.

Sarah, who also is a recovering alcoholic, came head to head with Paul after he previously mocked her for getting too drunk one evening.

And it's not just Paul she's come to blows with as the singer has also had numerous altercations with 'Ex On The Beach' star Jemma Lucy.
