I didn't know her before this show and think she's been really good, easily one of the most amusing HMs this year. If she keeps playing it like she is and doesn't get loud and involved in any nastiness I think she'll do well.
I cringed on LF when she said about Tiffany, "She won't start with me. She knows." Those sound like famous last words. Careful, Gemma, you've done all right so far, but if you think Tiffany is scared of you or respects you, then you could be in for a shock soon.
