UK Big Brother 2014: Five must-see moments from tonight's show

HELEN Wood can't go a day without throwing nasty jibes at her fellow housemates.

Tonight, viewers will see her blast Matthew Davies during a game of truth or dare – despite Mark's best efforts to calm the feud.

Meanwhile, Ashleigh Coyle strives for the Power, Mark Byron just wants his hair straighteners as Ash Harrison throws some insults of his own.

Here's our pick of the must-see moments from tonight's show: 

1. Mark Byron loses his temper

Pamper-perfect Mark is less than impressed when Big Brother is unable to turn on the hair appliances after housemates tampered with them last night.

Throwing a classic tantrum, the adorable Scouse fumes: "I’m going to kill each and every one of them, I swear to God. 

"They’re willing to let me walk around with a head like this.”   

Keep your hair on, Mark.

2. Ashleigh Coyle strives for the Power

We're loving this new feisty side to Ashleigh.

She told viewers she has a temper in her VT but Irish blonde has been brewing a storm – until now.

Talking to Toya Washington, she says: "How good would it be if I had the Power?

"Everyone’s looking at me being, ‘oh she’s so sweet and innocent, she’s such a young girl’. Jesus, I would tear s*** up in this House if I had the Power.”

We hope you're listening Big Brother?

3. Ash Harrison locks heads with Jale Karaturp

Following the screening, Ash reacts to Jale's nomination and says: "Jale was just chatting s***. F*** off, maggot.”

Taken aback by his cruel jibes, Jale says: "Wow, that's a bit of a strong reaction."

Just in the nick of time, peacemaker Mark steps in to diffuse the situation.

"Ash, you don’t need to say things like that to people,” he says.

We are yet to have a bad word to say about you, Mark.

4. Housemates play truth or dare – and then argue about it

It's probably the worst game to play in a house that can't keep peace for more than 24 hours.

Nevertheless, housemates decide to spice things up with a game of truth or dare.

First to remove himself from the game is Matthew, who decides he "doesn't want to talk about sex".

Apparently annoyed by his reaction, Helen says: "Oh for f*** sake, bore the f*** off! Bore off, bore off!"

May we suggest scrabble next time?

5. Helen Wood blasts Matthew Davies part two 

Still bothered by their truth or dare row, Helen moves to the garden for some fresh air – but Matthew follows her out there.

The pair throw unforgiving insults at each other before Helen explodes with shocking jibes after Matthew tells her to "get a boob job".

Helen fumes: “Boob job? Go rip your f****** hairs off your f****** pigeon chest you f****** skinny, scrawny, pale, plucked f****** pigeon chested t***.”
