The former escort is rumoured to be heading into the house

Big Brother is set for an explosive launch show tonight.

One of the women alleged to have had a threesome with Wayne Rooney behind his wife Coleen‘s back in 2010 is reportedly set to enter the house.

Helen Wood, 27 – who’s since become the owner of a beauty salon – was an escort when she and her pal Jenny Thompson claimed they’d slept with Wayne, 28, at Salford’s Lowry Hotel.

The mum-of-one is now rumoured to be one of 10 contestants getting ready to appear on BB.

Characters including an Essex boy, a Playboy model and an opinionated journalist will also be introduced this evening, while six others are joining as a surprise tomorrow.

Coleen, 28, was said to be ‘in pieces’ when rumours of Wayne‘s infidelity first emerged and is likely to be very upset about Helen being on television now that they have sons Kai and Klay together.

Those who know Helen have blasted her ‘awkward timing’ as footballer Wayne is currently training for the World Cup, which kicks off in Brazil next week.

‘The last thing Wayne Rooney wants to see when he is trying to focus on the World Cup is more headlines about him and her,’ a friend of the family tells the Daily Star.

‘Poor Coleen won’t be able to avoid the chatter on Twitter and the headlines. Our only hope is that she is first in and first out. Viewers won’t like her.’
