BIG BROTHER: Sara & Kathreya's Lesbian Kiss!

The Big Brother house finally witnessed its first kiss last night between newcomer Sara and cookie monster Kathreya.

Having got a little merry on homemade punch at a goth party thrown last night, the group decided to continue the fun in the swimming pool, prompting Angelina Jolie lookalike Sara to make a move on Kat.

She joked: “Kat wants to kiss me, we all know that. Are you ready Kat?” To which the terrified Thai responded: “No, I'm scared.”

Despite urges from the rest of the housemates, shy Kat refused, but eventually gave into temptation by planting one the newbie.

A delighted Sara squealed: “Kat kissed a girl!  I feel a connection with you!”

And it seems as though there may be more girl-on-girl action taking place with Kat suggesting: “OK. I kiss you tomorrow. Same time. In the pool.”

Could love be blossoming?
