Big bonk at Big Brother

Two teenagers have bonked their way into the reality TV record books by becoming the first people to have sex inside the UK's Big Brother house, beating the adults to the much anticipated act.

The pair, both 18, romped under a duvet, while fellow housemates slept during the filming of a youth version of the show.

The raunchy couple, Tommy Wright, from Weymouth, Dorset and Jade Dyer, of Great Yarmouth, Norfolk, were with eight other housemates in the programme being filmed by Big Brother makers Endemol for Channel Four’s education division.

The teenagers were locked in the house for 10 days. However, unlike the adult version they will not have their every move aired on TV and the show is being pre-recorded for viewing next year.

A Channel Four spokesman said: "There was a sexual encounter in the house but we don't want to go into detail about it because it's between those two people."

As for whether the saucy scenes will be shown, the spokesman said, “It’s a mid morning slot, and we’re not sure if it’s suitable for viewers at the time.”

Channel Four refused to comment further on the steamy session, except to say it wasn’t prompted by alcohol, since that was banned from the house during filming.

The TV station has yet to decide on the show’s exact contents, but it is expected to look at the challenges young people face while focusing on group learning, life skills, and career options.
