Big Brother 'geek' Bradley gets his first kiss

Leaked footage shows the self-confessed "geek" enjoying his first ever pash with Estelle after being challenged to kiss a fellow housemate in this week's "Yes/No" task.

Estelle presumably volunteered herself for the kiss, with promo footage for the episode revealing Big Brother opened the floor to any willing female housemate.

18-year-old Bradley has kissed two girls in the past but revealed, "They were both drunk so it doesn't really count."

He has previously admitted he could "grow attracted to a female member of the house" but wasn't so forthcoming when asked about a long-term relationship.

"I don't know about 'in love'," he said in an interview that appears on the Big Brother website.

Bradley is up for eviction this Sunday night but if Australia does vote him out, at least he will have something to be proud of!

Bradley and Estelle lock lips to cheering from their Big Brother housemates!
