Swapping partners: Big Brother love square gets more complicated as Sylvia goes for Dale

Sylvia, 21, appears to have switched her affections from new housemate Stuart to student teacher Dale, despite the latter's almost-romance with Jennifer.

After the house won their treadmill task, which saw Dale, Stuart, Sylvia and Rex recreate OKGo's pop video Here it goes again, they were awarded with alcohol - much to the delight of Rebecca.

Switching affections: Sylvia told Dale she would make a move on 'if she wasn't friends with Jennifer'

As the housemates began to celebrate one of their rare successful tasks, Sylvia took Jennifer aside and told her she fancied Dale.

Talking to imprisoned Dennis and Darnell, who were jailed by Big Brother for trying to guess who nominated who, Jennifer said: 'Sylvia wants to go for it with Dale tonight.'

As Dennis assured Jennifer that Dale wasn't interested in Sylvia, Darnell accused her of simply switching affections from Stuart to Dale to 'create a storyline' on the show.

After fighting off the attentions of Sierra Leone-born Sylvia, Dale also complained to the jailed duo about both women's behaviour.

Dale moaned: 'I don't know why she'd say it to Jen in the first place.

'The whole nation knows I like Jen. And now she's linking arms with him (Stuart).'

Dale insisted he wasn't interested in Sylvia - regardless or whether or not Jennifer was on the show.

He said: 'Whoever was in the House, I wouldn't. It's just not gonna happen.'

Appearing to become the agony uncle for the lovelorn housemates, Dennis told Dale that Jennifer trusts he wouldn't make a move on Sylvia.

Dennis said: '(Sylvia) just wants the airtime and the magazine deal.'

Meanwhile, on the other side of the garden, a boasting Sylvia criticising Jennifer for giving her blessing to her plan to seduce Dale.

As a confused Dale left the jailed pair to contemplate his feelings for Jennifer and Sylvia, Darnell complained the Big Brother house was turning into a teen TV drama.

He moaned: 'I can't take these talks, dude. This is OC s***.'

Dale's jealousy of Jennifer's friendship with Stuart grew further as the two ventured into the Diary Room together.

Speaking to Big Brother, Jennifer said: 'Dale obviously has a bit of an infatuation going on, which is very sweet. But it's never affected our friendship. We're still good friends.'

After leaving the Diary Room, Jennifer and Stuart go from flirting up a storm to criticising each other.

Describing Jennifer's make-up skills for the task, Stuart said: 'I know you do everyone's eye make-up badly so yours looks good.'

Jennifer fires back, calling Stuart 'evil', and accuses him of flaunting his six pack all day.

She said: 'You have your top out all day... It's like, "Ooh, yeah, look at my body."'

As Stuart attempts to calm her down, Jennifer replied: 'I don't need no reassurance, thanks.

'I don't really care what you think about what I wear. I dress for me, not for anyone else.'

Earlier in the evening, Sylvia and Dale bonded after starring in the treadmill task, which saw the pair wear bright clothes and make-up alongside Rex and Stuart.

After the task, stylist Jennifer focused on touching up Stuart's make-up in the basic bedroom, much to the chagrin of Dale.

Sitting together on a bed in the luxury bedroom, Sylvia leaned over to whisper something in Dale's ear, which soon stirred up questions with Luke and Rex, who were sitting in the room with them.

After her tete-a-tete with Dale, Sylvia erupted into flirtatious giggles and refused to tell the room what she had said.

Luke assumed: 'She said if Jen wasn't her mate, she would go for Dale herself.'

A smirking Sylvia replied: 'Exactly. You know it, don't you Dale.'

Despite the pair's flirting, Jennifer returned and announced she wanted to tidy up Dale's make-up.

As Jennifer suggested she liked men in make-up, Sylvia asked Dale: 'Do you wear it?'

A defensive Dale fired back: Do I f***. I don't even cleanse do I?'

After arguing of his hair gel, Dale called Sylvia over, declaring: 'Yeah, well I wouldn't worry about that (hair gel) becuase we passed, didn't we Sylvia?'

After witnessing the rapport between Dale and Sylvia, Jennifer sulked off into the garden to join Stuart.
