Do you mind if I boast a little here?!!
I was fortunate enough to bid the highest in the BB Auction for a cement handprint that Paul did just before he entered the BB house. (All the housemates did it and they were all up for auction in the end).
He signed and dated it and, well, I'm chuffed to bits I have something of his!!
I also bid high enough for one of the cushions from the house and it has pride of place on my sofa.
