big brother 15 final 4 'Big Brother 15' Andy's Head of Household nominations and Power of Veto resultsTime to find out who will be making the big decision this week in the “Big Brother 15” house. Read on to find out what’s going down or just sign up for the live feeds to follow along for the last week of the season.

Andy won Head of Household, as we saw on the Wednesday show earlier tonight. It appears that Andy nominated Spencer and McCrae, because GinaMarie’s key is in the Memory Wall. But we don’t know anything about Power of Veto yet, so we aren’t sure who is on the block at this point. We’ll keep you posted.

UPDATE:  It sounds as though either Andy or GM has won the Power of Veto, which means GinaMarie is safe — and we think it’s probably Andy who won. Of course, anything can happen, but we would bet Andy would leave his noms alone (and obviously GM would not use the POV on someone else if she won it). This also means it’s GM’s decision as to who leaves tomorrow night — Spencer or McCrae.

Who do you think she’ll evict? We’d think it would have to be McCrae. He has a way stronger argument to win the game than Spencer does.

What do you think, hamster fans?
